Based on what, Dave? Venezuela? I mean seriously, how many successful politically hard left economies can you name. Seriously.
How many times does your political standpoint have to be proven to be a failure before you will recognise it? 100 times? 1,000 times? High taxes, high regulation, state-interference with this ridiculous "we know best" ideology, has failed time and time and time again. And yet you *still* refuse to accept it.
And you accuse *me* of being brainwashed? It's really quite astonishing. Maybe you are only in your 20's or something and do no remember what shit we had to put up with under Wilson, for example? Or maybe you've just not read up on these things, I really do not know. But unless - as per Corbyn and McDonnell you are ideologically on some mission of hatred for the well-off, irrespective of how much you fuck everyone else over as well, then pursuing the sorts of policies Corbyn and McDonnell espouse, makes no sense whatsoever.
