> a wealth transfer to support poor rural American communities
My immediate reaction to this is: it's probably a wewlth transfer to the few landlords owning the land and probably charging higher rent, not to the communities.
Of course I haven't analysed the data. If I am wrong, hopefully someone will feel compelled to correct me.
My understanding is that it caused the price of corn to go way up, meaning the poor in Mexico found food far more expensive.
International markets and all that...
