Please define 'robbing'.
Bill Gates is very wealthy. Steve Jobs was as well. So are the people who own Walmart. I am not very wealthy.
I've given plenty of money over the years to help get Gates, Jobs, and the Waltons more rich. However, I've always given them my money willingly, and I don't recall ever once being robbed.
A good example of this is when the now defunct MCI corporation laid off $30 million worth of workers - then the next month gave themselves (the board of directors) $30 million in bonuses. CEOs have been lining their pockets with more and more cash while stripping workers of raises and benefits for the past 30 years. Now they say they've stopped taking from the workers (not much left to take at this point) but are making their largess thru stocks and other investments. Problem is, those stocks and other investments used to fund worker benefits like healthcare and retirements. So they are still being robbed.
Walmart is a prime example. The richest family in American (comprising 6 of the top ten wealthiest in 2012) is also the biggest welfare recipient - their employees are paid so little that many if not most are on some kind of Government assistance.
Steve Jobs - yeah made billions. By employing Chinese kids at something like 10 cents an hour to make his wares.
In California, the 1%ers complain about paying 40% of the income taxes. Seems to me that if you're taking 99% of the wealth, 40% in taxes is a deal. And wait till they finally eliminate the middle class. Then they'll be paying 100%.
Rich people don't create jobs or prosperity - consumers do. But consumers have to make enough to be able to afford the products they are making (i.e. consume). And they don't. That's why this economy has been stagnant for decades and the lost middle class jobs are being replaced by minimum wage jobs. Reaganomics works - but only for the 1%. The rest of us lose out.
