It’s how all centrally planned systems work. Avoiding accountability for failure is always the most optimal strategy, which inevitably ends up involving concealing failure. It was one of the defining characteristics of the soviet system. You can even see it play out in large companies (which essentially operate as miniature planned economies), where political actors promote bad ideas, and then somehow end up rewarded after they fail. The only difference being that companies in a free market (usually) have to suffer the consequences of their failures, and politicians in a democratic system can (usually) be replaced if they fall out of favor.
