Let me explain a scenario.
There are banks or financial institutions (I'll simply use 'bank' from now on) that give out loans for buying houses. They have their own risk evaluation criteria based on a potential debtor's credit history, income and savings. Now, going by each bank's own calculations, some customers are high risk (low income or low savings) and the bank would not typically lend them money. Now, the government sets out certain conditions and tells the banks that they must give out a certain % of their loans to people who are poor. Would you call that deregulation?
Secondly, I see this as a bonafide attempt by the government to help poor people get a house. I see this as a kind of socialism, because, by pure capitalist calculations, these poor people won't get a house, because, the banks who give out loans will only take risks up to a certain limit and seek to make profits.
Let me know what you think.
