A thriving capitalist country can still be fascist. Fascism isn’t just about economic decay, it’s a way for capitalism to protect itself when it's threatened. Even in a strong economy, if the ruling class sees socialism or worker power as a danger, they can turn to fascism to crush opposition and keep control.
In Russia’s case, the government serves capitalist oligarchs, suppresses worker movements, and wages war for imperial gain. Fighting between capitalist states, whether Russia or NATO-backed Ukraine, is not a fight for workers. The real struggle is against both systems.
