Money printed out of thin air becomes hard assets seized by failure to pay back exorbitantly HUGE unrepayable loans--- a brilliant greed and ignorance powered strategy. It is like playing a rigged gambling game with all the odds in favor of the house.
The longer the repayment is deferred, the higher the interest on the borrowed money becomes until the loan is called and since there is presumably no money to pay the loan back-- the collateral is seized. Legally.
