What you are describing as the state "siding" with the workers is what is called a "concession" because there was literally tens of thousands of them. There is still some legacy of the communist era left somewhat intact. The party is a bourgeois party through and through, it is a bad interpretation of what that means to assume that this would mean that capitalists should necessarily be above the (bourgeois) law. It wasn't just "corruption" they were guilty of, they were running mafias and murdering people. Even bourgeois nations prosecute mobsters.
