It didn't happen because workers were being paid too much for profits. No. Bollocks sorry.
That's not quite what Butch said, is it?
He stated that, due to the shift in the power-relations between the workers and the ruling classes, the workers were getting, in historical terms, an "upper hand" on their previous position, one that
eroded the margins that the owners of the means of production were used to.
This was indeed very much the case. It's why Sir Keith Joseph
et al inculcated Thatcher with a drive to destroy the various modalities through which the working class had traditionally expressed solidarity.
It happened because the bosses resented the workers getting paid too much.
Rather that they resented the power the workers had to demand to be paid what they considered an equitable wage.
The oil shocks of the 1970s allowed the Keynesian narrative, and hegemony, to be broken.
Arguably, the oil-shocks were "the icing on the cake" that had already started being baked in the 1960s to move away from Keynesianism. The oil shocks, being external, were easy to blame.
There's a reason I focus on neo-classical theory and evidence. 99.9% of capitalists are getting ripped off here too, and I don't think we will have a successful, progressive revolution without understanding this stuff properly.
Thing is, Capitalists don't mind being "ripped off", because Capitalism is all about the size of your slice of pie, and as long as you're able to retain the power to manipulate the system so that your slice is slightly larger than someone elses' slice, then Capitalism "succeeds", Capital can be accrued, and the wheel of consumption can continue turning.
