Whose poor decision is that? The banks created those products, the banks profit from them massively, and the banks receive the socialized bailout using
our money.
How exactly is being approved for a loan to buy a first home the fault of the purchaser?
We can shop in any grocery store trusting that the products are safe to consume. Meanwhile, banks are allowed to legally sell financial poison?
Sure, compare rates, terms, insurance, etc. But financial time bombs like you describe should be illegal. The banks should suffer the consequences of their greed. And the working class should not be left homeless as a consequence.
