Au contraire, it's far too easy to fire people in government for issues that have systemic root causes due to the nature of politics and public pressure. So the poor schmuck who pushed the button gets fired, and that's the end of it. No deeper evaluation or reports on how to prevent the issue from occuring in the future.

This leads to extreme aversion to any risk taking and creates bureaucracy.

This is opposed to the classic stories about junior engineers who lose their companies money, go into the bosses office expecting to be fired, and the boss says "why would we fire you? we just spent $X training you".
