Hey, if you can’t afford groceries, steal them. The world owes you at least that. Until we can survive without eating I will judge no one for stealing food so long it’s from the corporations and not each other. And many people this day agree with me.
I don't disagree on a moral level, but I don't think that "risk going to jail" is particularly good advice. If there's any social programmes or charities, see if you qualify before resorting to desperate measures.
