It's not about being "entitled" to anything.
I generally find the many alleged examples of public sector employees getting benefits and perks not available to the average American private sector employee to be unconvincing evidence that public employees are somehow living off the government largess.
But folks sleeping on public property and using public facilities to get out of paying rent is probably the example I'd be most sympathetic towards as illustrating that point. So in a sense it is about what public service "entitles" one to, especially when we're talking about the folks at the top of the pyramid making the rules.
