I don't know, but I find this very interesting, especially the 'negative interest rate' idea. I don't like the concept, myself. Someone is going to pay me to take out a loan at zero interest? Why? So he will have a supply of dollars coming in later, after everything has deflated, and he can buy everything up at bargain basement prices?
But if you have cash to lend, why not just sit on it until prices deflate, then buy? Is the goal to get people to default on the loans, and then swoop in like a vulture to seize assets? Probably, lol. (Just guessing here! Not an economist!)
