If you're not a young guy, I guess you just take it by what you see going on.
Fewer and fewer young adults are using their degrees. There are too many graduates and too few jobs. Meanwhile, H1Bs have taken many of the tech jobs, while other visa workers have taken others. The remaining jobs are not enough to compensate for the amount of highly specialized and skilled workers.
Illegal Aliens have contributed to wage reduction and have taken over the few labor intensive industries that haven't been a victim of de-industrialization via "Free Trade".
Thus, this leaves few options: 1) Self Employed, 2) Government Jobs, 3) Low brow Service Jobs
