from a non-biased perspective

This is difficult. I see a lot of people recommending Mises, Hayek, Rothbard, etc. These are PROFOUNDLY intelligent men, but I would not consider their teachings to be unbiased, as other Nobel-prize winning economists (eg Keynes, Krugman, Bernanke) would consider their findings to be incorrect.

All economic models are based on assumptions that are probably not true in general, and all the findings are based on those assumptions. Keynesian theory is incredibly popular today for example (virtually everyone but Libertarians think the way Keynes did) and yet Keynes's ideas were basically disproven during the period of stagflation experienced in the '70s.

Another thing that most economists don't consider is the morality of fiscal policy. From a philosophical end, perhaps we can reduce unemployment by engaging in deficit spending- but OUGHT we? In the short run it makes better lives for today's voters in today's economy, but in the long run it's our children and grandchildren that will be forced to pay back that debt- with interest. What are the moral implications of this?

Are financial and civil liberties connected? This is a question that every libertarian asks himself, but it is not something that every economist asks.

I recommend Khan Academy's video tutorials on macroeconomics- it primarily teaches Keynes (whose ideas are primarily used today) but not without reminding you that his model is based on bad assumptions, and how it could work the other way.
