It's not a recent thing, and certainly didn't start with Corbyn (although he may have accelerated it).
I agree that it's neither recent, nor started with our lord and saviour JC, but is there any reason why you think he would have accelerated disillusionment amongst the working classes?
There have been polls (I think on here somewhere) showing Labour's approval rating amongst traditional working class dropping at a greater rate since JC came in.
I guess it's arguable whether a lower approval rating does signify disillusionment.
Ah, I get where you're coming from. And yeah I'd say they are different things. Disillusionment is a malaise which I think one can safely put at the feet of Blair and Brown.
