I think the problem here is that fate spamming has allowed TONS of people to hit 50 with a battle class while completely ignoring money. Even with questing you have gear and other goodies tossed at you in such a way as to render all crafted gear 1-49 a luxury and unnecessary.

Once the gravy train has ended and there are no more easy quests like, talk to person X in zone Y, wow that was tough so here's your 3 allagan gold pieces, people are now stuck with high end gear requiring large repair bills and super expensive materia with no clue how to make money.

There are plenty of ways to make huge amounts of gil with only a battle class at 50 but since fates don't teach you how to spiritbond gear or sell tomestone ingredients people are at a loss.
