I hadn't really thought of it this way, but that's a common thread through so many political problems of the last 20 years. If you can convince enough voters that immigrants are the problem and you are the solution then you can do anything you like.
The question is, what are we going to do about it? If we keep ignoring the condition of the working class for too long like in this country, you get Trump and the likes.
It's an enormous failure of our political class to have ignored real issues for so long, getting it to the point where pretty much the same thing is happening all around the world, and the plutocrats and billionaires are exploiting it because they can since they have all the power.
Not even a new thing, Rage Against The Machine wrote songs about all of this 20 years ago, it's just that most people weren't paying attention.
You can do better than such a low effort swipe.
