The financial collapse occurred mainly because Clinton repealed Glass-Stegall and the greedy little bastiges saw that as an opportunity to rake in as much money through unethical schemes. Canada didn't allow what Glass/Stegall prohibited, which is one good reason FOR some regulation. The government doesn't need to crawl into every orifice we have, but because people just can't be relied on to do the right thing in all cases, it's clear that some governance is needed. The problem is that we're governed by people who are as bad, or worse than anyone outside of government.
Socialism isn't just about tax rates, it's having an over-abundance of government programs that are designed to make everyone equal, rather than allowing people to have an equal shot at succeeding in life. When people ignore opportunities, the government steps in to provide for them and their families, at the expense of the tax payers. When the government decides "At some point, you've made enough money" (Obama said that), they take more. With net worth of ~$40 Million, has he made enough?
I'm in favor of regulating industries and entities when they prove they need to be steered away from screwing competitors and people. The problem is that there's not 100% agreement that someone is being screwed, nor that someone's actions are intentional.
