People in the UK who are against immigration are often talking about Poles who moved to the UK after the EU and not Indian families who have lived in those neighborhoods for generations.
And they DO have families of their own here (and bring over their in-laws), and a lot of them don't integrate well, for a variety of reasons. At least a third of my neighborhood is Indian. They glare at me on the sidewalk when I wave. And most of them remain inured in their caste system, and are difficult and unpleasant to work with.
Again, all the same arguments about developing our own chips domestically -- which I doubt many people have a problem with -- apply to developing our own, better education pipeline to fully develop domestic software engineers.
