The "wealth distribution" is entirely at CAH's expense. They only surfaced that language because they made a point of communicating to the non-recipients that they wouldn't be receiving anything on top of their original contract (of getting the game for cash, which they totally got).

I realize I didn't clarify explicitly. While I'd agree that a one-time $15 gamble would be an irrationally exorbitant expense if it was in place of a family meal, I think we're talking about different things.
Even if "poor people" were <$1000 away from financial ruin, $15 towards a reusable entertainment asset is quite different than $15 towards one-off lottery tickets.
