Such cheerfulness can only be maintained if one has a near-total absence of any critical reflexivity and a capacity, as he had, to cynically comply with every directive from bureaucratic authority.
Capitalism requires pure reflexability in order to be cheerful or happy. The only way you can do this is via an almkst impossible, super anti-cynasism. You cannot, at all costs, question what has been assigned to you, else you'll understand that everything is a farce. Reality must be easily fungible in order for capital to thrive, as reality catches up fast and deems certain action unsustainable. Constant adaption is constantgly required for capital.
