A vocal part of the far left wants open borders; doesn& #39;t believe in national citizenship; & indeed would abolish the nation state. In doing so, they would destroy the only practical means by which global capital might be restrained & democratic controls be imposed upon the market
They would say that they want to reimpose such controls at a more global level - but in practice such an attempt a) would be undemocratic, because no supranational/global demos exists and b) is total pie-in-the-sky in anything other than the very long term, and probably even then
The reality is that slogans about & #39;international socialism& #39; and abolishing borders and nations mean & #39;socialism never& #39;. Indeed, they mean that even moderate social democracy is a pipe dream. They let their utopian fantasies block anything like pragmatic wins for working people
And this is why the arguments of someone like @PaulEmbery cannot be disentangled. If you want something like a social democratic economic programme, it makes no sense to oppose the nation state and want to abolish borders. They are the means by which such a programme is achieved
