I agree, but I also think the moment has passed. If there was a time for a working class (lexit) voice it was during the referendum. It was always going to be difficult establishing that alongside the other groups calling for brexit, most of which were nationalistic or even racist - ukip, tory right etc. Where we are now is going to play out as a harrumphing conversation about sovereignty and the constitution, with staggering levels of hypocrisy on both sides. But underneath all that is really the weakness of organised working class politics. Labour under corbyn didn't managed to deliver either a working class voice or politics around Brexit. I suspect he was probably being honest when he said he'd reached a remain conclusion and saw that as in the best interests of 'working people' or somesuch, but that was all still a universe away from engaging with the real alienation working class voters felt towards the whole political class.
