Yes, I agree. I'm not sure what the limit is (if any) on numbers of terms that U.S. Congressmen can have. My uncle had eight terms, and could have remained longer. He retired because of my aunt's illness.

The U.S. limits presidential terms to two terms of office. And some states do not allow a governor to succeed him- or herself.

U.S. Supreme Court Justices have life-time tenure. Only death or retirement (or impeachment?) can end their terms. In a way that diminshes political lobbying or control, but it is still there in the appointment and confirmation process and in the background.

Sometimes I wonder if you had a computerized lottery which drew names from all the world's population to be the political leaders for a short length of time, would there be any real change for the better? You'd still have the civil servants who really run the show.
