What in the world?

So I have been calling around for a few jobs to be done around the house like sprinklers being fixed and repairing my front entry way and can I just tell you it is not fair!! These guys are charging, so far, around $50 AN HOUR? Who makes that kind of money? They are not even including the parts!!! I have a college degree and I get like $18 dollars an hour, Seriously, not fair. It is almost tempting to quit my job and fix sprinklers for a summer. Each summer I could make as much as I do working year round! WOW!!!
