Actually everyone want's what immigrants provide. They want people to pick their fruit, clean their hotel rooms, and a variety of other crappy jobs for minimum wage or lower and sure as hell don't want to do something like that themselves or have their kids look forward to that as a "career". They're all happy to have people who pay into SS and Medicare without ever becoming beneficiaries. They're happy to use products produced by Google and Microsoft and Adobe, and devices with chips made by Global Foundries, to name just a handful of companies led by immigrant CEOs; getting the intellectual top 1% of every third world country is beneficial to everyone even if they're too anti-intellectual be able to grasp that.
I picked fruit in high school for a summer, with immigrants. Thank god I didn't have to feed myself let alone my family on the proceeds. I'd challenge anyone who says they don't "want" immigrants to come pick fruit for a living with me for one day, just one day. After that we can engage in an intelligent debate over if you "want" immigrants or not. Until then, those who say they don't "want" immigrants are simply speaking from a position of profound ignorance.
Wrong, immigrants consume more welfare than they consume.
Wrong again, the only non immigrants who want immigrants are the ones who can profit off of them. For those who lose their job or income which would be the vast majority of non immigrants, it is a cost not a benefit.
The ignorance is monopolized by immigration proponents in Europe right now. Hopefully, they continue to learn slowly since the whole fracas has been endlessly entertaining.
