I think if a game is in any way competitive, paying money for extras should automatically require you to compete only against others who paid the same amount.

I think if a game is in any way competitive, paying money for extras should automatically require you to compete only against others who paid the same amount. Then it becomes a challenge based on who spent the same money the most effectively, and not rich kids decimating people with less time or money to invest. In addition, EVERY TIME a purchase is being made, the game should be required to remind the user of how much money they’re really spending, by comparing the purchase to something common (like food). For instance: “The $9.99 you are about to spend on this one-time-use box of gems for this one game could also have bought you lunch today. Proceed?”.
