He wants to eliminate the FED and various departments like education!
The Federal Reserve is one of the main players in the economic crisis. They set interest rates too low, and print too much money, which results in a vast expansion of credit and high inflation, which leads to greater mal-investments, and, thus, larger recessions/depressions.
The department of education has a terrible track record, and is illegal. Under the constitution there are no provisions for such a department, and the department also violates the 10th Amendment. Ron Paul wants to give the ability to educate back to the states. You will still have your public education systems, but they'll just be run a lot better, and your local schools won't be dictated to by some pencil-pushers in Washington.
He wants to get rid of student loans
He doesn't want to get rid of student loans, he wants the Federal government to stop backing them. Kids will still be able to get loans, but they will have to be private, or the individual states can back them/offer subsidies, or whatever (as some do). Government backed student loans increases the cost of education, as the universities have a guarantee that they will get their money, so they charge whatever the hell they please. Government backed student loans distort the price mechanism, and are the cause of the trillion dollars of student debt.
He doesn't believe in Climate Change (granted, the whole Republican Party hates science)
What does it matter if he doesn't believe in climate change? The free market naturally decarbonizes, anyway, so let it be. I'm not going to get into this, anyway, as the point of Ron Paul's philosophies is that it doesn't matter what he believes in.
He is against the Civil Rights Act!!!
