The March on Washington for Jobs and Freedom in 1963, as well as the whole Anti-Vietnam War movement, were both associated with Boomers ('63 would have had some young boomers), and were both heavily class conscious. I think on one hand you had industrialization as well as "strong unions" at this time, which Boomers took for granted as they entered the workforce. Simultaneously the institutions in the US were weeding out and destroying the notion of class in any analysis of public life and political economy. Within this context you get the neoliberal revolution in the 70s-80s, a bipartisan consensus towards the machine of the political economy, and then deindustrialization and the shift to service economy, which hollows out vast holes in the working class. In combination with the Taft-Hartley act the workers have no politics to address changing this political economic arrangement, and politics instead becomes focused on the things that are on the table, like culture war, identity politics, etc. We've been stuck on the train ever since, and even with the crisis of neoliberalism, the parts still function and our politics becomes this increasingly absurd spectacle focusing on cultural signifiers around the rotting corpse of the neoliberal consensus, leading towards doom.
