Way to Survey-Way to make money at home, paid surveys

Who makes more money (excluding endorsements) Floyd Mayweather or Peyton manning?? How about Floyd Mayweather or Reggie Bush??

if forex brokers charge no commissions, then how do they make money. how do they charge the traders money based on pip spreads or bid/ask price?
so if forex brokers only make profit on the spread, then that means that the trader isn't paying the broker anything? and the more a trader trades, the more the broker makes? that true?
