"Most of these charges that people pay are economically unnecessary. There's no real cost behind them. There's no real value behind them. So, they're what the classical economist called empty pricing. Prices with no real cost value. What they called rent and fictitious capital. Capital claims on junk mortgage borrowers. The pretense is that all these debts can be paid but it's all fictitious, because everybody knows - at least on Wall Street everybody knows - that many debts can't be paid."
