This philosophy has real PR potential, IMO.
I've always believed Europe will turn away from international leftism, and when it does, it will be in the blink of an eye.
The appeal of Leftism has been "We will get the Rich to share their wealth with you". The voters now realize that what is happening is that THEY are being told to share their income with the underclass of the entire world, and it is NOT an appealing prospect any more.
The Western natives need to be made to realize that, to the people in the Third World slums who want to invade the West, THEY are the Rich who are to be plundered.
