Let them be responsible for themselves. It doesn't help you to criticize others.
If they were responsible for themselves, they would be working or starving right now. However, they are on unemployment. As a taxpayer, I'm partly subsidizing their donut and lotto habits. That gives me ample reason to criticize their behavior: if someone is spending your money, you're perfectly entitled to at least complain about how they spend it.
Please, if you don't like the system, argue for a different system. You aren't going to change the behavior of these people by putting them down.
