Ummmm.... this is embarrassing to the us government and agencies.... so most people never heard about this....
Sorry to say, except rejoice in the truth finally, yes, the u.s.government and agencies thereof were responsible directly and in a way forcfully.
What american, what farmer, what banker would dare go against them ?
There was one wonderful book, long ago, long forgotten,
about the protocol/ trained / enforced corruption of the american farmers.
It's title was something like farmer's folly, or the folly of plowing, or something like that.
Yes, yes indeed, the united states government took charge early on (corruptly),
and so was responsible for the dust bowl, wholly accountable to God for what happened to the families, and to the land (not just there, but as God says much much more also) .
