That's true if and only if the spigot and the drain is equal across
all levels. Which generally is not true. You get to the highest
level and a lot of the drains go away.  So what happens then? My
feeling is that inflation goes up, the price index forces the cash
rewards to drop. This means that you're penalizing the lower level
players the most. What used to give them $10 may now give them $1,
but the drains: training costs, etc, are still high.

In most games, the majority of the player-held Cash reserve is in
the highest level players.

No, it would lead to needing even more new sinks, because if you
don't curb the cash at the higher levels, inflation will drive the
lower level players right out of the game. Or else you get into
government subsidies ;)
