What gets you up in the morning? Is your goal achieving new heights and creating something grand or making it a day closer to retirement? Although a rash generalization, incentives for most government positions are rooted in the beliefs of the sixties working at the same job for life. Long-term, tenured employees are good, but only if their goal is to better the organization and, in turn, grow themselves.
Most corporations want people to take risks to compete with rivals and gain market share. However, governments do not have competition. A huge incentive for change is missing. Marking time and concern over rocking the boat in order to get a pension does not help projects move forward.
Democracies Versus Oligarchies
Many of us live in democracies. Personally, I love this form of government. However, it is not the ideal place to get something done. Too many people have to be pleased. People cast votes to make decisions and set directions.
In a democracy, people (in reality, it could be a majority) can still disagree and fight a decision they just voted in again, impeding progress. The difference is that in a democracy there is no CEO. Governments do not have the concept of "disagree and commit" that is a staple in the corporate world. Corporations are oligarchic societies.
When the decision or direction is wrong, the company loses money. If the executives do that too many times, the company disappears. In corporations, mismanagement's reward is failure.
