If a law can only possibly impact the poor, then that law is effectively written to impact the poor - the purpose of a law is what it does.
If you make it illegal to sleep on the street at night (by extension, sleeping anywhere that isn’t a legal residence), you are de facto making it illegal to be homeless.
That a law applies to everyone is not a “universal defence” in its fairness.
The primary problem others have with ICE is thuggish enforcement and lack of accountability, especially when reckless.
But your problem seems to be a combination of the wealthy having an easier time accessing the US (agree, but many countries have purchasable visas), and poor illegal immigrants having no other option (partially agree, but not all illegal immigrants are poor, and many who are do have alternative places they could go legally).
