If you think people signing a contract for a mortgage know what they are getting into, then you don't know people. The first 10% is illiterate, the second 20% numerically illiterate and then there's a huge partition that just doesn't understand the math and the options. People are being taken advantage of, because they don't know what they are getting into.

Then they should seek the advice of a professional before signing a very large contract in the form of a mortgage. Executives shouldn't be held responsible for people who don't read fine print or who fail to understand how mortgages work.
