It's not that we approve, heaven forfend, of this particular policy idea but we do insist that this is the point behind Brexit:
All of which is significant. Corbyn and McDonnell are smart enough to understand the risks of Brexit, but they also see it as an opportunity to push through their own economic agenda. Which is why they are exploring the freedom Brexit would provide for public ownership, lower rates of VAT to help those on the lowest incomes, state aid to support sunrise industries, and fair trade agreements with developing countries.
Remainers on the left would argue that there is no need to leave the EU for this to happen, but they are wrong about that for two reasons. The first is that a radical socialist programme that included a different approach to state aid, state ownership, public procurement and managed trade would be deemed illegal under European law. The second is that without Brexit, the impetus for change would quickly dissipate.
No, we really don't think that a more socialist economy is the way Britain should be moving - but you knew that, right? The underlying idea is entirely correct though. Membership of the European Union cuts us off from the possibility of a number of useful and interesting economic policies.
We would like to see, for example, unilateral free trade. That's not something which EU membership allows. Not with that great big wide world out there that is. This is a policy different in kind from that socialism above of course - it has actually been tried and it worked, unlike socialism anywhen anywhere. We ourselves did it in 1846, that free trade thing, and we prospered mightily as a result.
Brexit allows us policy freedom which EU membership doesn't. Yes, that includes damn fool things like socialism but we are indeed all adults aren't we, capable of making up our own minds rather than having to rely upon Brussels to do it for us?
