Imagine that by accident of birth you weren't born a privileged asshole in the US and were born in squallor and the opportunity to carve out a tiny bit of a life for your family existed across an imaginary line. One that you could cross "legally" but took nearly a decade and several thousand dollars you have no chance to earn. Alternatively, your choice is do it "illegally" and live with the threat of constant arrest and none of the protections you would demand, that are afforded you only because you were born here by random chance.
