I don't know - I mean, I've seen/know of players who've spent obscene amounts of R/L money opening gamble/loot boxes - although I'll concede that, in some cases, it's a byproduct of a gambling addiction.
Eitherway, If you want to point the finger at people having too much disposable income and "not being smart" with it, look at that sort of MMO player who does that sort of thing first.
