Right now the Pride fighters get paid more. The momentum is starting to shift with the UFC bringing in more money from shows and Pride losing sponsors along with their tv deal. in a few years the UFC will likely surpase the UFC in terms of pay.
Caning Dana White would be the wordt thing they could do as is the master mind that took the UFC out of Dark Ages and into what they are now. If it wasn't for him the UFC would have gone bankrupt as they were hemoraging alot money back than.
