What is the pattern here? It begins with the banks, and it ends with the banks. The lenders at the banks have degrees in banking. They know what homeowners can and can't afford. The homeowners, in many cases, are not that savvy. They are factory workers, construction workers, restaurant workers, and other non-monetary trades, who don't know economics. It is up to the banks to separate those who can afford a loan from those who cant. After all, that's what they went to school for, and got their degrees in. Instead, they lied to the homeowners, convincing them that they could afford what they couldn't. They also falsified income statements and other paperwork in order to push their loans through, and make the bank money. In addition, they threw in hidden charges, which the homeowners had no idea existed until they had to begin paying them. The banks especially screwed most of our soldiers and vets who were buying their first home. Then, when the loans began to go underwater, they falsified documents in order to make illegal evictions. Throughout the process, the banks were acting as a criminal enterprise.
But, according to you, it's all the homeowners' faults. You know, there is a difference between free markets and criminal markets. There is also is a difference between supporting free markets and supporting an ongoing criminal enterprise.
