That’s a good post @39thStep as, I’m well aware that I can hold all of those apparently contradictory ideas (and more) simultaneously
My take on the apparent contradiction of capital wanting immigration and yet, at the same time their political wing drip feeding the racist divide and rule is explained by the differing supply side needs of the economic base and the electoral imperative of the political superstructure.
Throughout my lifetime, and probably yours too, immigration has grown the economy but also been a go-to wedge issue for the right seeking electoral power.
Having successfully divided the working class, the broader national identity element of the “culture “ is, IMO, there to hide or subjugate class antagonism.
So, for me, the apparent contradictions are just that, apparent. Everything above is consistent with accelerating neoliberal forms of accumulation and regressive transfers of wealth.
