They seized land. Seized the land off of prior settlers. Farms foreclosed by the spade. They couldn't grow shit. Dust bowl. Tumbleweed. Government stepped in. Entire towns became ghost towns.

Did they provide them enough rope? They mass injected the land with dumber populations, importantly selling land rights, only to reclaim it, what also changed then was mass immigration as well, but it caused immediate pressure on resources like the ground water, fertiliser. Causing drought, as temperature rose. Was it accidental. I don't believe in accidents.

It went on for 10 years, those dust bowls, and the great depression, a viscious cycle, as wealth gained more land far more land.
