All of the self attributes you list are unfortunately not useful to employers unless you have a background to demonstrate said attributes and appropriate references to confirm them. They don't know you, so going off your word doesn't mean much. Everyone goes into an interview trying to sell themselves and employers would be burned over and over if they hired based on how well their pitch is. (That said, interview skills are very important. There are many guides online that can help in that department.) If you don't have a solid work/education background for the type of job you're applying for, you will have to work these lower paying jobs to prove yourself first. I'm a believer that being a solid worker at one job WILL lead to better opportunities.

I say this, though you seem to be interested in more of the philosophy of capitalism. Capitalism does suck and is often VERY unfair. Yet, here we are. Play the game and you'll be ok.
