Any Robinhood of the new ages?

Well we all see disparity of wealth across the world
my question stems from an observation which says that the wealthy giant can get unfair advantage -then how will the balance come .. without empowering thw wealthless he will not gain more.. so he shall empower and eventually gain more out of them , as a cycle have quite a control over the circulation -- considering many of the wealthy players lobby to join hands (eg: the property owners/construction guys)may bend policies any be at an unfair advantage say for span like decades..this perspective may appear familiar but is a question ..once again to judge the incompleteness of this thought process..
