Difficult, but not impossible; and it just depends on what sort of lifestyle you want. And benefits shouldn't be a lifestyle choice, it should be a situation you're in till you can get yourself out of it.
But as many on benefits enjoy doing nothing, they do black market stuff to supplement the "I'll stay at home culture". A lot of the single mums, hold Anne Summers parties, do Avon sales and all sorts of things. The younger ones seem to deal in pills and stuff. The pregnancy rate dropped recently, and one thought is that kids no longer get an automatic entitlement to a 2 bed flat. It was also thought that social media had played a part, and there seems to be a slight drop in the areas that don't teach sex education, but I agree, it's a complicated situation.
But I think a telling scenario, is a school friend of 16 year old daughter, who is having issues with her parents, and having heard both sides of the argument it's just normal growing up rebelion stuff; except social services and her councellor have basically told her that if she gets pregnant, then they'd have to rehouse her in her own flat.
