The system doesn't benefit the few at the expense of the many because those few are benefiting society more than anyone else. They contribute more than all those who buy those products. If everyone were getting the same paycheck you wouldn't even have a toilet paper or a tampon (like it was in the Soviet Union). Any company will be just losing money instead of profiting and any business transaction will come to an end. And the technology would not be progressing. So everyone will lose. The poor will just be poorer and won't be able to use all the products we now take for granted.
