I think you would be able to get a *better* understanding of economics from your own reading than from going to university. A lot of mainstream so-called economics is actually illogical nonsense. A classic example is Keynesianism. I have found, after geting an education in economics on my own, that many people educated in economics are just spouting fallacies that have been refuted over and over.
You can get a good grounding in economics, enough to critique all the main stream schools, from reading just these three books:
"Economics in One Lesson" by Hazlitt
"Human Action" by Mises, and
"Man, Economy and State" by Rothbard.
For example, one of the common fallacies is that mathematics is necessary to any advanced understanding of economis. Mises totally destroys this error in two pages of Human Action. Those asserting, or rather assuming the wonders and necessity of mathematics *never* answer his argument, because they can't. Their belief system is actually just a welter of fallacies that they can't defend, covered with a thick layer of mathematical gobbledegood that adds no explaining power whatsover to their theories, which cannot withstand critical scrutiny with or without mathematics!
I promise you that, when you confront the orthodox with the fallacies that you have learnt to see in them from the Austrian, they will *never* give any rational defence of their magic-pudding worship of big government, and all their replies are an amalgam of the following fallacies:
- assuming what is in issue
- appeal to absent authority
- personal argument.
It's literally that powerful. You can demolish professors and academics with this stuff, which shows that they are basically just in the pay of vested interests, high priests preaching that Pharaoh can do no wrong, even as he robs the masses blind.
However getting understanding is a completely different proposition from geting a degree.
Basically there's a whole college course on the mises.org website for free. Best to check it out in detail, and ask the advice of people in there who will be sympathetic and knowledgeable. But reading only those books I cited should take you at least a year, and then only if you devote regular time to studying them.
