As someone that has a cleric with crafting skills (herbalism) and was going to get blacksmithing and woodworking before I slowed down on my playing, I can easily make some serious coinage spending a few hours making critical healing potions and those can sell up for 1k a bottle if you're patient enough to sell them for that. If you buy your herbs, the profit isn't nearly as obscene, but gathering your own herbs is just straight cash. Seriously, you (the reader) should give herbalism a try, it's real easy to make potions once you master it.
But even that had plenty of time sunk in before I got to the point of mastery I can crank out critical healings like it was nothing. Pick pocketing didn't have that in it's original form and while I'm not against the profit margin, it was fairly easy to go under the radar of the in-game authorities. Last time I'll mention it, but making it as lucrative as it once was in a highly populated area with people contesting over it like the publique will create a lot more RP than just making the loot table as it is right now.
The thieving meta will constantly change, as gendarme will get smart enough to use see invisibility stuff to catch thieves running around in invisibility to shirk the downside of failing pickpocketing.
Crafters, or rather herbalists and veteran blacksmiths (the current jump from copper to steel right now is obscene cost-wise), will have the money alongside the ninjalooters, merchants, and the odd adventurer that actually finds ar'akir on max spawn (lol).
