I live with my parents, so once you factor out the cost of bills and a mortgage, autism bucks is actually a high paying job, I have managed to save more $$$ than a couple who both work but have to pay most of it on a mortgage and childcare.
I realise not everyone is so fortunate to have parents cover all their costs though, roll of the dice I guess. But even if I had a gf, I would want to remain a NEET for life. As bad as life can be, I can't imagine anything worse than being stuck in fucking traffic at 8am on a Monday morning.. I'm still asleep at that time.
To the point though, I love drugs and it's not right to assume all NEETs are dirt broke.
