That's the problem innit. Not so much the who to get to do it but who is the 'we' who get to do the trusting.
So I'm sort of in favour of destroying what we have and hoping something better arises. And if not, starting again. Apocalyptic-communism. I do realise this is not very pragmatic.
Aside from that... I think Marx was right in that we're headed towards that state anyway. It's just so painfully slow. So... being a bit more pragmatic, it's down to producers of culture to, at least, question current conditioning and expose illusions and that, I suppose.
