Whoa there, cowboy. My Rogue most certainly cares about gold in a most profound, some say lascivious, way. I the player don't particularly care though.
Given the multitude of economic difficulties young people face including student loans, the rise in housing costs, and the fact that real wages have not kept up with inflation, I think maybe they just view wealth as such a fantastical idea that they can't suspend their disbelief and include it in a game. A fire breathing dragon? Ho hum. A crab-like mechanical device you get inside and pilot? Yawn. A young adventurer with no debt and plenty of purchasing power? That's just totally unrealistic.
