You know, income inequality is a problem, but I don't know a single person, including those who are upper class, who fit into this category. My network is full of hard working people across the income spectrum.
I currently work for a little more than minimum wage myself, but you know what? That's okay. I am young and have few marketable skills, I will keep building those, and chances are, I have a good shot long term just as almost any non-lazy, able bodied person does.
Maybe all of the 500+ people I know who are hard working members of the middle class are just lucky, or maybe people should spend less time complaining and more time working hard to build skills and provide value to their clients and/or employers. If I was a manager or business owner, the guy moping around complaining about how poorly paid he is would be the last to receive a raise.
Most wealthy people are hard working, and I know several who you wouldn't even know are high-income because they bust their backs and live modest lifestyles (they are also kind, generous people). Now, thanks to the Federal Reserve, there are people who sit around making millions from the artificially high stock market, but that's the exception (and you can take advantage of the stock market too).
