It may not have the moral high ground, but you&#x27;d better design your systems to deal with it, rather than pretend that  it&#x27;s possible to stop it.<p>Also, people moving to seek a better life for themselves and their children is pretty core to the existence of the US, so I would posit that it&#x27;s a moral thing to do if people aren&#x27;t breaking any other laws.  By making legal immigration easier, you keep people on the side of the law and less tempted to break other laws, since, hey, in for a penny, in for a pound.
