Economists say every immigrant is a net economic positive to the nation. They eat,buy food clothing, cars. Every immigrant child is a net negative to the state,at least until they turn 18. But it isn't even. Net neg per kid of maybe 800 a year, positive of each adult of 1200-1600 are the numbers I've heard on freakonomics podcast. Their guests proposed solution was to have the feds pay the states per an immigrant child to offset who bears the costs. I don't think it's even a debatable position that each immigrant is a net economic positive, in the long term. Some political groups worrying about losing their culture is a completely different kettle of fish.
