1. I think the answer to your first question is to maybe stop the nation-building in the first place. We wouldn't have to worry about affording crap if it doesn't exist.
2. I understand the viewpoint of the pro-regulation politics, but to say that our country somehow resembled capitalism is a joke. In fact, I agree that regulation is necessary to protect rules of the game, and I agree for regulation in the right areas and places. The housing market and the crisis was not a result of unfettered capitalism and lack of regulation. There was PLENTY of regulation, and there was a framework that had previously been set up by the almighty government. It was not a free for all. A framework and environment that encouraged risky behavior was laid out by the government. I agree with those that those on Wall Street fully knew the potential catastrophic results of their actions. But when banks have been bailed out at a more than 90% rate, why WOULDN'T they have performed them. The very fact that you acknowledge that "this is assuming we don't need to bail out banks" is also acknowledging that the almighty regulators were doing so in the first place.
"The 50 largest failures up to that time all took place in the 1970s and 1980s. As the savings and loan (S&L) crisis unfolded during the 1980s, government repeatedly sent the same message: lenders and creditors would get all of their money back. Between 1979 and 1989, 1,100 commercial banks failed. Out of all of their deposits, 99.7 percent, insured or uninsured, were reimbursed by policy decisions.16"
99%. 99 percent got a bailout. That is not capitalism. That is an artificial environment created by the government.
I recommend you read one of the better papers written about the crisis and the environment surrounding it. It's actually a great laymen's paper as well, but it does get a little dense. It's 40 pages, and well worth the read. It criticized the environment that government set up, as well as executives and Wall Streeters. But the message that runs clear is that Wall Streeters didn't create an unstable system, they merely took advantage of one with perverse incentives where the "loss" part of "profit and loss" was non existent. It is impossible to run a market effectively without the notion of loss.
