Capitalism creates plagues!

This is funny and interesting:

Historically, the plague arrived after the invention of the chartered corporation, and after central currency was mandated. Central currency became law, and 40 years later you get the plague. People got that poor that quickly. They were no longer allowed to use the land. It shifted from an abundance model to a scarcity model; from an economy based on annual grain production to one based on gold released by the king.

That's a totally different way of understanding money. Land was no longer a thing the peasants could grow stuff on, land became an investment, land became an asset class for the wealthy. Once it became an asset class they started Partitioning and Enclosure, which meant people weren't allowed to grow stuff on it, so subsistence farming was no longer a viable lifestyle. If you can't do subsistence farming you must find a job, so then you go into the city and volunteer to do unskilled labor in a proto-factory for some guy who wants the least-skilled, cheapest labor possible. You move your whole family to where the work is, into the squalor, where conditions are overcrowded and impoverished — the perfect breeding ground for plague and death!
