Wealth is produced. If there were a fixed amount of it, we'd all still be nomadic hunter-gatherers. Therefore, the gain of wealth is NOT a zero sum game. When some CEO (good, bad, or hopelessly incompetent) makes 14 bazillion dollars, that does nothing whatsoever to take anything from you. You don't need to worry about what that CEO makes. You need to worry about what YOU make.
Consider the White House Chief Calligrapher makes $96,725 per year. What a complete and utter waste of tax money. If it were not for the fact that its our tax money, it wouldn't matter a hill of beans. If Microsoft or Apple wanted to hire a Chief Calligrapher at $96,725 or $967,250 it wouldn't matter a hill of beans except to the shareholders of each company who might not think such an expenditure is going to pay off all that well.
