Your Book Review: Progress And Poverty

Illustration courtesy of geoliberal This is how it's possible to have urban blight and slums in areas with extremely high land values. Even if there's a temporary dip in prices, speculators know that if they just keep HODLing the general trend – absent a local collapse – is that land value always goes up. Here's George: Take now... some hard-headed business man, who has no theories, but knows how to make money. Say to him: "Here is a little village; in ten years it will be a great city—in ten years the railroad will have taken the place of the stage coach, the electric light of the candle; it will abound with all the machinery and improvements that so enormously multiply the effective power of labor. Will in ten years, interest be any higher?" He will tell you, "No!" "Will the wages of the common labor be any higher...?" He will tell you, "No the wages of common labor will not be any higher..." "What, then, will be higher?" "Rent, the value of land. Go, get yourself a piece of ground, and hold possession." ...without doing one stroke of work, without adding one iota of wealth to the community, in ten years you will be rich! In the new city you may have a luxurious mansion, but among its public buildings will be an almshouse. I don't think it's a coincidence that real estate is one of the oldest investments on Earth and the principal concern of basically every war ever. V. The Problem Solved We had two questions at the beginning of this book: why are there industrial depressions, and why poverty seems to advance alongside progress. You guess it, it's all because of land and rent. By George, industrial depressions are caused by land speculation Speculation has a tendency to press the margin of production down until it's just past its limit, forcing labor and capital to accept returns so small that it actually hinders production or ceases altogether. The saving grace is that as long as the population is growing and/or technology is improving, productivity will go up, and production will start again. But soon enough the land values go up. This drives speculators bidding up the price of land, anticipating future even higher land values, which stresses the productive margin again. So you get a cycle – productivity rises, economy booms, land values rise, production stagnates or stops. No matter how complicated or sophisticated the economy gets with layer upon layer of financialization and abstraction, when you unravel it all George says this is the ultimate cause. Periods of industrial activity always culminate in a speculative advance of land values, followed by symptoms of checked production This is how you get the baffling situation where able hands are eager and willing to work, capital is ready to employ them, natural materials are abundant, and yet the laborers are idle and the factories stand empty. So that's it for industrial depressions. What about the other paradox of poverty advancing alongside progress? By George, poverty advances alongside progress because of rent The reason why, in spite of increase of productive power, wages constantly tend to a minimum which will give but a bare living, is that, with increase in productive power, rent tends to even greater increase, thus producing a constant tendency to the forcing down of wages. George backs this up with several pages of specific regional figures demonstrating how land values have continued to explode all over the world. By George, on average and in the long run, no amount of hard work from labor, no force multiplication from capital, no increased gain from co-operation and specialization, no labor-saving invention or increase in personal efficiency, work ethic, or morals, can escape the long reach of rent. In short, increased power of production has everywhere added to the value of land; nowhere has it added to the value of labor; George notes that the mass die-off of the Black Death in England in the 1300's significantly reduced the productivity of the individual laborer, and yet wages went up. That's because the decreased population also caused a massive drop in competition for land, in turn causing rents to plummet. (For more detail on this read about the Peasants' revolt, also known as Wat Tyler's rebellion). George says the opposite happened during the reign of Henry VIII, who seized the lands of the church and those held in common by the peasants, and handed them out to newly minted aristocrats, which was followed by suppressed wages. In the reign of Henry VII., half a bushel of wheat would purchase but little more than a day's common labor, but in the latter part of the reign of Elizabeth, half a bushel of wheat would purchase three day's common labor. He sums it all up like this: Material progress cannot rid us of our dependence upon land; it can but add to the power of producing wealth from land; and hence, when land is monopolized, it might go on to infinity without increasing wages or improving the conditions of those who have but their labor. So there's our answer: the monkey wrench that causes the boom-bust cycle of industrial depressions is rent, and even though we have more than enough material wealth to provide for everybody's needs, rent prevents us from distributing it fairly and equitably. Volume II Okay, The Rent Is Too Damn High, and now we finally know why. What are we going to do about it? Insufficiencies of Remedies Currently Advocated George goes down the list of everything we've already tried and why it hasn't worked (or has worked, but less well than we hoped), which you can read about in Appendix C (there's a link that returns here at the end): Appendix C: The Insufficiency of Remedies Currently Advocated The Remedy George says the solution is to make land common property. He doesn't want to confiscate land, or force everyone to live on some giant hippie commune. He proposes instead to let everyone continue to "own" land exactly as they do now, but we should impose a special tax to neutralize the perverse incentives of land rent. He anticipates a lot of pushback on this, and promises that his remedy: Is just

Not bubonic plague; that one is another distraction. The reason we don't get more Black Deaths isn't because yersinia pestis died off or mellowed out. It's because we have good sanitation and pest control.

A little backstory: in my younger days, I thought it might be fun and useful to learn the entire history of the world. To that end, I started with accounts of archaeology and prehistory, then the ancient civilizations, classical antiquity, and so on until I lost momentum somewhere around Tamerlane and the Black Death.
H5N1: Much More Than You Wanted To Know
January 01, 2025 · Original source
<1% chance it’s more than 100x as bad (unprecedented) If you multiply the 5% chance of an H5N1 pandemic per year by the 7% chance of severity ≥ Spanish Flu, you get an 0.35% chance of a Spanish Flu level pandemic this year - one in three hundred. That’s a little higher than base rates - the last pandemic as bad as Spanish flu was smallpox hitting the Indians circa 1500. If we don’t count that one (where would our conquistador equivalents come from?), then the last equally bad pandemic was the Black Death in the 1300s. So we seem to get that level of pandemic once every 500 - 1000 years; a 1/300 chance suggests a 2-3x elevated risk. The Spanish Flu killed about 50 million people. A second Spanish flu could kill more people (because the population is higher), or fewer people (because medical care is better). If we assume those two cancel out, and that a second Spanish flu’s death toll would also be 50 million, then a 1/300 chance of 50 million deaths = 166,666 deaths. In some weird probabilistic expected utility way, about as many people will probably die of H5N1 next year as died in the past year of the Ukraine War. You will have to decide whether this is a reasonable way to allocate mental real estate to different catastrophes. Other Considerations Even if H5N1 doesn’t go pandemic in humans for a while, it is already pandemic in many birds including chickens, getting there in cows, and possibly gearing up to get there in pigs. This will have economic repercussions for farmers and meat-eaters. The CDC and various other epidemiological groups have raised the alarm about drinking raw milk while H5N1 is epidemic in cows. There is an obvious biological pathway by which the virus could get into raw milk and be dangerous, but I haven’t seen anyone quantify the risk level. Epidemiologists hate raw milk, think there is never any reason to drink it, and will announce that risks > benefits if the risk is greater than zero. I don’t know if the risk level is at a point where people who like raw milk should avoid it. Everyone says that pasteurized milk (all normal milk; your milk is pasteurized unless you get it from special hippie stores) is safe. There are already H5N1 vaccines for both chickens and humans; pharma companies are working hard on cows. First World governments have been stockpiling human vaccines just in case, but have so far accumulated enough for only a few percent of the population. If H5N1 goes pandemic, it will probably be because it mutated or reassorted, and current vaccines may not work against the new pandemic strain. Some people have suggestions for how to prepare for a possible pandemic, but none of them are very surprising: stockpile medications, stockpile vaccines, stockpile protective equipment. The only one that got so much as a “huh” out of me was Institute for Progress’ suggestion to buy out mink farms. Minks are even worse than pigs in their tendency to get infected with lots of different animal and human viruses; they are exceptionally likely to be a source of new zoonotic pandemics. Mink are farmed for their fur, but there aren’t as many New York City heiresses wearing mink coats as there used to be, and the entire US mink industry only makes $80 million/year. We probably lose more than $80 million/year in expectation from mink-related pandemics, so maybe we should just shut them down, the same way we tell the Chinese to shut down wet markets in bat-infested areas. ACX grantee One Day Sooner is trying to help the FDA get more resources for Operation Warp Speed style pushes that could expedite approval of pandemic-related vaccines. ACX grantee Duncan Purvis is trying to improve existing influenza vaccines in ways that could make them more effective. ACX grantee Blueprint Biosecurity is working on pan-viral suppression techniques. Conclusions / Predictions All discussed earlier in the piece, but putting them here for easy reference - see above for justifications and qualifications. H5N1 is already pandemic in birds and cows and will likely continue to increase the price of meat and milk.

Your Review: Joan of Arc

The French were saved from immediate disaster by three things. The first was the Black Death, which killed a third of Europe. This had effects wildly beyond the scope of our story but also demolished the tax bases of every state in Europe. This shrunk the size of armies and thereby as an incidental side effect meant that all existing castles were heavily overbuilt, since they were intended to defend against half again the force that would actually be present, which slowed the pace of war tremendously.
