Of course wealth is power. If you have 10 million dollars and I don't, you have more power than me. You can do many things I can't. But perhaps you did cancer research for 20 years and found a cure for cancer while I spent my money on vacations and partying. This incentive acted as it should. The world now has a cure for cancer. We can't now say that you should have the same wealth/power as me because power/wealth is bad.
