When your access to food, housing, heating and healthcare for your family are dependent on your income, you may find yourself facing very difficult decisions. Most parents will risk whatever legal ramifications to care for their kids and that's inherent moral and ethical, even if the downstream outcome is not. That is because it is the socioeconomic system rather than the individual who is acting immorally.
> The law is the law, and there is no excuse for breaking it.
This is an infantile view. The law is a framework and there are lots of circumstances where breaking it is not only excusable, it's the only moral action.
