Why don't we just simply End Welfare for Immigrants / Illegal AND Legals?

That way we can say ok come here all you want i guess but there isnt going to be any food stamps , or free healthcare , or section 8 housing , No tax funded programs for any legal or illegal immigrants Period -

I'm willing to bet that would pretty much be the end of immigrants coming here except for maybe drug dealers or criminals then we can just arrest them and either rfid chip them and send them home or send them to camp fema for a Long stay
