If we want good government, then we need civil servants who are willing to work their whole careers in government. If we want good military officers then we need people who will devote their whole life to the military. If we want good park maintenance we should hope for people who are willing to live their whole lives as park rangers. If we want accurate budget projections, we need accountants and economists who are willing to commit their whole lives to understanding the relationship between government policy, taxes, and the results on the budget.

Term limits won't get us there. We need to go in the other direction.
