Capitalists cannot solve or improve the materialist conditions of people nowadays, they steal, plunder, lie, murder, bomb etc. Only a worker's party can truly improve a nation's wellbeing without resorting to awful exploitation. The capitalists always pander's propaganda to the general populace in order to divide people's into lines of hatred, the populace of Russia, and the collective west are told to hate each other, any deviances or questioning this hatred would be questioned and punished, similar to how wartime ww1 and ww2 created ethnic hatred amongst workers belonging to imperialist countries.

I suggest reading Das Kapital as introduction on how the capitalists continuously abuse the populace. Or maybe read a quick summary if you don't have the time.
