Furries come in two varieties: the NEETbux variety who collects their tugboats, and saves up all their cash for their fetish. If they still reside with parents, its usually a long-suffering mom or grandma who pays the bills, and makes sure to carefully separate their food on their plate, lest the autist sperg out. If they live on their own, its likely in some sort of subsidized apartment for speds. They may also have just enough savvy to do art of their own, which other degens will cough up cash for.
Then there's the barely manages to function around other humans enough to get into STEM, usually IT, variety. Like their NEETbux cousin, they prioritize their shekels towards their fetish. They also may have enough savvy to do their own art, thus pulling in more cash.
Note that in both versions, art style may vary wildly. Usually, its pretty shit, because male coomers are s hit at art in general. If its a rare female autistic coomer, the art may actually approach good.
