I feel like a lot of old-school left-wingers and Marxists in the boomer generation were just people who fell into workerism and productivism, which I don't really see as Marxism. Forming a fetishistic attachment to "the working man" is an ideological foil to hegemonic classism based on consumerism, but in the long-term it is counter-productive if the long-term goal is the abolition of wage-labor via decommodification. It can also be weaponized ironically to divide the working class, even as this ideological phenomena occurs precisely when class consciousness is in the process of emerging among them. Given that, it is not surprising how even some working class boomers that partook in the old left end up with reactionary views in old age, particularly in questions of law, enforcement, rights, etc.
