But the crisis have made banks gone bankrupt (in Greece & USA, and I think more in the future), so they are not so invulnerable than that, despite the effort of the FED to make it otherwise by devaluating money.
This freaking system is artificially drawing smart people in finance, when they could create new business and job instead. (Remind me a book called "smart people should build things")
However, nowadays is the best period for the poor to become rich.
You don't need capital, only an internet connection.
Their is a skill shortage (http://www.zerohedge.com/news/2014-08-29/employers-arent-just-whining-skills-gap-real), and you can learn everything on internet, especially in the computing industry.
This is the great thing of the knowledge economy, and would thus transfer wealth from stupid rich to smart poor even faster. This is what I mean by "being the victim of his inferiors".
If you mean become rich in fiat money, then it is still the same old game where bankers positioned at the top. You can't earn money without bankers first release money at higher level. Even there is a skill shortage, without money that shortage will not translate into income
I just realized recently that money has never been generated by free market choice, it is always an imagination in people's mind and bankers/governments create money to fit this imagination: People think money is a measurement/unit of value, and the more you have the more things you can buy. Then as an authority they create this unit of value as money, give it a value and then people are satisfied. Since people need money to measure the amount of value, they seldom notice that the value of this unit itself is changing
