I think it depends. Many traditions aren’t centered on material gain at all, so many practitioners end up living pretty simple, humble lives. And that doesn’t mean they aren’t living their best lives.
That said, those who practice certainly get help, spells, rituals, better opportunities, fewer setbacks, helpful connections, etc. So a lot of things will go in their favors. That naturally translates into more money or stability.
For me, wealth isn’t only cash, it’s about accumulating a lot of occult knowledge. For example, if someone’s making lobster, I may get them to invite me over for dinner. So that’s 3 lobster tails, a bunch of beers, and 2 entrees. That meal could cost me a good amount of money, but I can get it for free. So wouldn’t you say that’s better than being wealthy and still having to pay full price for it? Or doesn’t that make me wealthier in a way, because I get the meal and keep the money?
Jokes aside, it really just depends on how each practitioner defines wealth, and how much is enough for them.
