It's a question of incentive alignment. Managers are not dumb, their incentives are aligned to short-term success rather than long term. Consider the difference in scenarios between producing ok code very quickly and good code more slowly. The manager will immediately feel the negative consequences of taking the second decision, if their incentives are badly designed. Meanwhile they may never feel the negative consequences of the first decision. When bad code breaks down, how likely is the manager of three years prior the one to take the blame or heat for it, let alone face real consequences? Often they won't.
