if they 'stole a loaf' and left the house it would be ok but they are moving in to the kitchen to have constant access to the loafs, thats what makes it a problem. once they make it across the border, they still have to maintain decades of illegal lifestyle. the legal framework doesnt let them achieve a normal life where their hard work will afford them a decent life. the struggles and difficulties continue for them and keep pushing them into illegalities. just letting them in illegally doesnt solve a problem. it starts a long chain of other problems that sometimes ends up with them being deported 20 years later.

Is it wrong to steal a loaf of bread to feed your starving family?

It might be illegal, but it is morally right.
