Socialism, Free Enterprise, and the Common Good

If the collapse of modern society depends on the disappearance of the middle ranks between the apex and the base of the social pyramid, if it is dependent upon the absorption of these middle classes by the extremes above and below them, then its realisation is no nearer in England, France, and Germany today than at any earlier time in the nineteenth century.
I can't tell you how many border threads I've been on that have seen the same thing said. Our open borders and 20 million illegals will destroy the middle class. It all comes full circle.
