Don't you think that is a little harsh on the borrowers? I mean not all buyers were well informed and the lenders weren't going to straighten them out. It is very easy to get swept up in the storm when trying to buy a house. I went through that and there were tons of offers out there and i almost chose the wrong one because they were all pushing the ARM's or an 80/20. Luckily we had a really good agent who told us to stay away from them so we got a 6% fixed rate.
Again, there's nothing wrong with any of those options depending on your situation.
