Sorry, but you are mistaken. Costs will continue to rise, while revenues in poker (per table) cannot. The cost in real dollars will eventually overcome table revenues. Not soon, but eventually it is inevitable. Other businesses simply increase their prices. Poker cannot raise their prices without losing customers as it would be too expensive to play. Who will play 3-6 holdem with a $10 rake?

Dealer salaries, despite being minimum wage are costly. Add their health insurance costs, business liability costs, the cost of the employer tax portions for FICA, FUTA, Workers' Comp for every employee, expenses of operations and maintenance, drinks, the very rare comp, and other casino wide cost allocations (security, porters, cashiers, etc and the total will eventually overtake revenues. I am sorry to report all this but I work in the financial field and know of what I speak.
