What is economy?

I don't understand anything about the economy at all. It's just one of those things you hear about constantly but never know enough about to understand it. I would love to take a class about economics. Until then, I know nothing. If someone were to force me to be president and fix the economy, I would certainly would not legalize drugs or prostitution like so many other people would. Money is not worth giving up the health of Americans and the well being of women. One thing I would hope to do is stimulate the renewable energy industry. It would help create jobs and sustain them as long as we are dependent on those forms of energy for our homes and cars.
