I think that is blaming the victim. As the article says, you have repair people describing the terms of the loan to people. If they don't understand what they're selling (and I'm sure they don't) then how can you expect the average person to? Not to mention the pressure selling that is probably being used on targeted groups (I'm looking at the elderly, minorities and groups that are generally less financially sophisticated).
Most people generally aren't in a position to "vote with their wallet". This is because most people are leveraged to their eyeballs with rents. This is a problem with Wall Street that trickles down, not a problem with the consumer that worked it's way up.
> many consumers took on home loans they had no intention of ever making good on
I disagree with this as well. People generally are not scam artist. On the contrary, most people like paying off their debts. Were people probably overly confident in their ability to repay, sure. Saying that people intended to default however, is not true.

Wall Street (and it's derivatives... I'm looking at you, ad funded Silicon Valley) is full of fraud. The fraud stems from the fact that the only people who can realistically perform checks and balances on this group(s) are the groups themselves. You may be able to blame the consumer when they have full and clear knowledge of how the system works, but that's not the case. Wall Street is full of so many obscurities and 40k ft descriptions that the average consumer really has no chance.
A good example of how the average person thinks financially... how many homeowners do you know that consider their home an "investment". Probably most, if not all.
