In other words, all of this is not brought about by myopia, but simple business decisions.
Fully experiencing bay area traffic for the first time, I was pretty annoyed, so I went into 1. my national bank of multiple years, 2. a local credit union, and 3. The dealer itself to try to get a brief loan so I could get a nice sportbike. I make a decent salary, and have been working since I was 13.
Every single financial institution made me fill out my residence history for the past two years, which (on their paper forms) was a several hour process and a huge pain in the ass - why does it matter where I lived when I was eighteen? I'm not sure I remember the names of the people I was living with, much less the landlord's secondary phone number. It seemed especially pointless with my main bank, because they had full historical data on my salary, and knew damn well that I could pay off the loan in full with a month's salary.
Long story short, all of these places denied me for not having lived in the same house for multiple years. I waited a week, got a bonus, and bought one from a different dealer in cash. The next time I need a loan, you can bet I won't be going to any of the companies I visited previously.
It's ridiculous to make financial judgments based on length of residence at an address in 2013 when there's so much more accurate data available (actual income/purchasing data). I think this is a policy that's going to change - many if not most of my highest-earning peers move around frequently to meet needs of the modern job market.
There's definitely a mix of opinions out there on this, but there have been some good challenges against community lending targets as a significant cause of the crisis.

Wikipedia can sometimes provide a pretty good record on controversial topics with sufficient visibility.
The current article on causes of the US housing bubble, and specifically the section covering loan policy, cites useful literature on both sides. While it's not a completely one-sided argument, it appears the weight of the evidence goes against the CRA and similar government initiatives as a leading cause of the crisis: http://en.wikipedia.org/wiki/Causes_of_the_United_States_hou...
At the very least, given the number of other sections on that page, you should conclude that the CRA wasn't the sole cause of the crisis.
Note from the same page, (and in some of the above polemics), it seems like there's a similar cry to blame deregulation for the crisis. There are reputable economists, even Bill Clinton claiming that the repeal of Glass-Steagall probably wasn't sufficient to cause the crisis. Regulation and deregulation make suggestively convenient bogeymen for the right and left respectively, so they should draw a sort of heightened scrutiny.
Events like this are naturally complex. Alarm bells should ring if anyone boils down the entire crisis to something so simplistic as "too much or too little government." Some problems and some solutions don't fit conveniently on a postcard.

Hell, I'm having trouble keeping a steady place to live because I'm an intern in the Bay Area for 2 months at a time. Housing market is too hot for anyone to have offered rentals even loosely timed to what I needed.
