Start that chart on Jan 1st, 2008 and it would show a very different picture. One where corporate profits are very volatile and hence demand a higher rate of return than wages, which are rock solid on the graph. You're comparing apples to oranges with the two, it's like saying muni's should be getting the same returns as tech stocks.
By the way, nothing's stopping you from starting a company and being part of the corporate profits side of that line. I did, and have profited from it far beyond what I could have if I'd stayed a salaried employee. However I took substantial risks and worked my ass off to get to that profit, neither of which would have been required if I'd stayed in a salaried job. With greater risks come greater reward. If you spent half the energy you spend bashing "the man" and dreaming up conspiracies building a company you'd be rich by now!
