Why not?
Immigrants produce more for the US economy then they take in "welfare" and there is no reason not to support them being able to draw from programs they help fund because immigrants do pay taxes folks. The American anti-immigrant sentiment isn't very different from the German antisemitism in the 1920s, many Americans blame immigrants for Americans being worse off, and think that something needs to be done about the immigrants stealing American (white peoples) jobs it's a clear scapegoat mentality.
Immigration should be restricted because many of them don't assimilate.
If they receive any Taxpayer funded services they should be deported.
But to be fair I would like to eliminate the welfare state for all people!
Is not assimilating a bad thing? 7 of the men who signed the Constitution were immigrants. Much of the culture of America is based on those of nations such as Mexico, England, Scotland, Germany, and the Nordic nations.
But isn't the usage of roads a "taxpayer-funded service" and how do you argue against the fact immigrants work harder, for lower wages, then natural-born citizens with immigrants committing less crime and being generally more receptive to the "American dream" these sound like model citizens in a Conservative America, but why are you so hostile towards them?
