Communism has nothing to say about the current situation that Western countries find themselves in.
On the most basic level, what “Capital” is there to seize?
The machines that make machines i.e. Capital are all over in China, Vietnam, Mexico. If seizing these machines was the means to prosperity and a dictatorship of the proletariat, then it would require invading these aforementioned countries.
But that is impossible because these countries are framed as the good guys, the resistors of the Colonial White Supremacist order. So, even though they have the Capital, and Communists are supposed to go seize the Capital, they are unable to, because that would be a Colonialism Racism.
What then can Communism offer then other than just self-contradiction?
Even the much simplified populist-communist premise of “Eat the Rich” doesn’t work because “the Rich” can just pack their bags and move to Israel at the drop of a hat. And going after them would be an Anti-Semitism, so once again, you’re at square one.
The only group of people that you’re allowed to target then are Whites who cannot flee to other countries and who have a little bit more money than you do i.e., whatever is left of the middle class. And that’s exactly who the organized Left targets.
