What facile tripe. You are misusing the word "own". What other, more accurate, but still delusional , lefties say is that a given small percentage of people "control" 90 or more percent of the wealth in America.
That's as dumb as saying the president, members of congress and the supreme court "rule" 100% of America.
Controlling stock in publically traded companies, or having an executive position at a company doesn't mean you "own" the company. Nor does it mean you can sell off your stock or liquidate the company's assets and either buy a yacht or give it to Obama's PACs to buy him a better shot at re-election by ignorant independent voters. Acts like that would throw lots of those "laborers" you mention out of their jobs, with no capital.
