I've never understood the idea of being mad about what another industry is making. They make more money than you? Great go put in an application. Don't want to work in that industry? Then maybe they deserve the better pay. If you truly think you are that superior to the other industry then use their pay to bargain at your own job.

If you're a nurse who's working long hours at a job that requires an education and you're getting paid the same as a McDonald's cook, don't be mad at the cook, be mad at your employer. Go to them and demand a raise, and say I could work there for the same pay, spend more time with my family and not be responsible for keeping people alive. Pay me or I'm going to peace out.
