The next generation is far more likely to vote Right, especially in the UK. They don't even understand progressive ideas ('Public services? What's that then?') never mind believe that they're worth supporting.

And Munchau, who seems to be an idiot, seems to have forgotten that the hippy boomers have reliably shifted to the Right as they've become older. Maybe not as Right as their parents, but certainly a long way from their teenage radicalism.

I think this article is really saying the exact opposite of what it seems to. It's not so much that the Left will prevail, but that there's still a danger that the steady rightward march may be derailed before it becomes unquestioned and absolute.
