Will this bring about trouble?

Alright. First post here. Anyway, ive been playing/hosting the same group of guys for about a year now, no problems. I would in all honesty put me at the top, with my best friend right behind me(4/5 times, me and him are heads up) Anyway, tommorow is my birthday, and just for fun we're going to start a tradition that everyone chips in and pays the buy-in for whoever's birthday it is. One kid(who claims he is the best, but there are some better then him) is complaining because 'i make the money so much, that why should i get a free entry' We try telling him that he'll get his free buy-in his birthday, and so will everyone else, but he's still complaining. Should we just can the idea, or keep with it and not care what he thinks?

BTW, this is a 60% social game, 40% competitive game
