There is method in democrat madness to openly advocate socialism.
There are tens of millions of immigrants now in the United States and it traditionally takes generations for children of immigrants to achieve comparative economic status with native Americans.
This huge influx of immigrants will look around at the cornucopia of plenty surrounding them and decide that they would not mind the government giving it to them and would comprise a huge voting bloc.
The second generation in the USA starts transition.
It turns the old ideas of immigrants on their ears. It once was mainly for people with advancement mentality. Then it got dumbed down to career menial laborers. Now it’s charity cases. And if we want to do charity, most such operations are better done while the person is in their own country.
