Question about the Falling Rate of Profit and Reforism

my question is related to the tendency for the rate of profit to fall as outlined by Marx. Im not theoretically well versed in the marxist concept but to me I understand it as corporate profits decline as capitalism expands due to increased competition and the minute increases in productivity that can be accomplished year over year and therefore quarter over quarter for investor reports. This leads to a crisis and therefore capitalism needs to expand through exploitation of imperialism to reap greater profits of cheaper labour and resources, lenin outlines this in Imperialism.So given that capitalism and imperialism are a historical development from productive forces, capitalism is a motion, i believe marx outlines this. And also given that social democracy and the social welfare state are historically contextualized as a tool to combat the threat of socialism in the imperial core, why do reformists believe in 2020 that we can return to a vibrant welfare state when the tendency is for the rate of profit to fall and we don't have the historical context of the threat of socialism?i see Global neoliberalism as not a "choice" but a economic motion of capitalism due to the rate of profit to fall as well as its historical context, the fall of the greatest international socialist power.In my question I'm more concerned with how this relates to the rate of profit and not the threat of proletariat rev. in the imperial core.International corps are not going to be able to restrict profitability in imperial core countries through a return to regulation of the FDR period as it would plummet profits and therefore the main driver for capitalism.solidarity! via /r/communism https://ift.tt/2ZCozcl
