I've taken exactly two courses of economics, one on Microeconomics, and the other on Macroeconomics. I understand a lot of the basic economic terms, but there's one thing I see conservatives saying all the time that doesn't sit right with me:

Government cannot create wealth, only redistribute (or destroy) it.

When I look for someone explaining why, the answer always is the same: all the government wealth is taken from the wealth people already had.

Okay, I give. What is wealth, and why can't government create more of it, when kids with a lemonade stand can?
