I'm baffled why you would construct such a false dichotomy. Unless you're lazy, it's easy to work to feed your kids. The only way that doesn't hold true is if you're the victim of violence to prevent you from working...and once you're the victim of violence, morality no longer applies. It'd be like asking "Is it moral to do X" to escape a kidnapper. All moral responsibility falls upon the kidnapper, not you.
