This isn't the way to fix this problem. Any game that restricts progress based on the the value of your spend instead of the skill level of the player is not going to do well long term. What struck me at the Clash of Clans world finals was that some of the players there who won substantial amounts of money had actually spent zero $ on the game. They were not told they couldn't compete in the finals or barred for that reason. This is like killing the dream of a small club winning the FA Cup. There must surely be a better way than this.
