It's the right to be an asshole.

Prior to the welfare state, you couldn't be an asshole to your kids because they wouldn't take care of you when you were old. You couldn't be an asshole to your neighbors because they wouldn't lend a hand to help you. You had to be friendly and personable to others to establish relationships such that people would miss you should you die and want to help you.

Today? Gibs. You don't have to be normal, you're entitled to other people's stuff. They don't have to want to give it to you, the state will put a gun against their head and take what they can get away with
