Not a problem. The feds will allow those foreclosures to happen and people will lose the homes they never could afford to have bought in the first place.
The banks and finance companies that lent them the money will go bankrupt also,but that's no problem either because the international banks will step in to buy the debt for a penny on the dollar,so it won't be long before they are up for rent again.
This happened the first time in America at the end of the War of Northern Aggression,when the yankee bankers came in and bought up 10's of thousands of acres of farm land for back taxes.
Happened again in the 1930's,and will be happening again soon.
Funny how that works out,ain't it? If you didn't know better,you might almost think that was the plan to begin with.
Wash,rinse,repeat in another 30 or 40 years,and no one will ever remember it happened before.
