Canada's economy is heavily invested in the primary sector, though. The main point I'm trying to make is that these political decisions are heavily dependant on the society in question.
For the most part, having more regulation is a good decision. So a politician in the US decides the same thing and proposes a piece of legislation to regulate, say, the banks. It may be a good decision, but it won't pass into law because it's a smart move. It'll get passed into law if it jives with the majority's values. If ideologies, no matter how ignorant, get in the way with sufficient force, it won't succeed. Likewise, bad political decisions have a lot to do with the culture in question, the people the politician is surrounded with.
