How would term limits stop the use of insider information for an individuals benefit? I would opine that would aggravate the situation more since reps would try to get as much as soon as possible since they are limited in time.
Secondly how exactly would term limits address abuse of office for the same reasons.
You're right that politicians would try to get as much as possible. Human nature being what it is, they would do it in any time frame so it would be prudent to limit that time. Same for abuse of office.
Nothing is exact, it has to be tinkered with until we get the results we want.
Couple term limits with insider information laws and strict restrictions on lobbying post-government as well as some of the other ideas mentioned in earlier posts.
Knowing heavy restrictions on profiteering and power exist might have the benefit of attracting better candidates for public service.
