Yes he became really rich but the net sum of wealth he provided in return has made everyone else much richer than him.
You are making the wrong conclusion that you are worse off "materially" if such smart individuals didn't innovate. In fact you and everyone else in america would be slightly poorer.
Most countries do not even have a "good economy" that they can brag about. The fact that you want a larger portion of the massive wealth these people have brought to america is an really entitled opinion to have.
America is an an midst of an economic boom which is almost a miracle obama has pulled ( compared to its EU/Asian/SouthAmerican Counterparts ) . If you are unhappy that america is also home to some of the richest and smartest individuals on the planet and you are trying to compare yourself to their standard and saying "Uhh, I want some of that" then its a problem of mentality and not about wealth/immigration/politics/etc.
