It depends on the timeframe obviously, but $10k is hardly cheap.
As a Japanese gamer says, paying for games is like dining out. You get nothing useful after a good meal, and paying for games may as well be more useful.

Of course, the best outcome is not to be addicted.
(I'm also not sure it's actually true, either - would depend on what metric you use)
