People are intelligent enough to recognize whether a representative is benefiting them or not. They will not vote for someone who is using his privileged position in the legislature to enrich himself or build a fiefdom of influence. Rather, legislators will only be able to stay in office so long as they do what their constituents want. If legislators are maintaining their power by other means, such as institutionalized corruption and force, it is not because there are no term limits on them, but rather because of other fundamental problems of government in those states.
