We should analyze liberalism from a materialist standpoint and not treat the ideology of it as the primary factor. On the surface level, Lula and a lot of American/European soc-dem liberals will theoretically have the same philosophy, stated values and preferred policies. But the labor movement will be stronger and more principled wherever the concentration of industry and the proletariat is the highest. The semi-bougiefied imperial core proles have much more trouble staying principled or properly understanding the course of politics. The labor movement in the imperial core is coasting by on pure inertia from previous decades. Their gains are eroded by ever increasing rounds of austerity.
