Another person missing the point - This isn't work! It's a game! The vast majority of people who buy gold/gear with money have done their work for their wealth, and are using some of it to pay for their happiness. Stop trying to equate this to their real lives!
I'm not missing the point, the game is an extreme microcosm of real life for some. A fair number of the people buying gear are probably using their mommy's cc (not crit chance).
That being said, I firmly believe the RMAH is a scapegoat for the real culprit in the game, gold and the GAH. Gold needs to be worthless because it's guaranteed to drop. The guarantee of gold from play time guarantees gold farmers, which guarantee flooding the economy with gold in addition to the rare find.
The drops might otherwise be rare enough to make botting unpopular, but the gold guarantees profits.
People can't seem to understand that and every time I post about it, I get hounded by trolls riding trolls wearing troll shirts.
