What's wrong with these people? Don't they realize they ALREADY have it finally good?

Some people always want more. Everyday normal people do this. You have probably thought about having more yourself and may not have realized it. You get your first job outta HS making 20,000. Then you ask yourself, well what if I could make 30,000? Or double it and make 40,000? So you go to college and get a degree and start making 40,000. Now that isn't enough, now you want to make 60,000. People think of this everyday. With making more money comes the cost of life and sometimes a little just isn't good enough. People are idiots!
