Well, in canon you need to pay for food—although it’s mentioned that you can cast enlarging charms o food you already have. Aaand … that’s kinda it. Water, free. Shelter free. Furniture, free.. Transport, free. Magical artifacts, to be fair, will cost you somewhat, so entertainment, medicine (is it mentioned if St. Mungos is public healthcare?), and certain conveniences (owls, broomsticks, floo powder …) will require a least intermittent income, but I would say an unemployed wizard is still quite comfortable compared to a muggle. And most magic items will last for years or decades, judging by the Weasleys.
I think that most people can’t do that.
