NBA: How do the lakers afford all their players' contracts?

Salary cap is the highest price a teams total salary can reach. So say its 50 mil and anything over that is ticketed with the luxury tax. Where the team has to pay dollar for dollar how much they go over. SO say they go over the salary cap by 5 mil they must pay the mil to the player and pay an extra 5 mil to the nba for going over.The difference between say the cleveland a small market team and the lakers is even though the cleveland is sold out every night the lakers have more income from merchandise, food, etc.. THink about how many people have a kobe bryant jersey and etc. So lakers have extra revenue from all that to pay the luxury tax. Unlike other small market teams that dont have that luxury they cant go over.
