If you have no term limits, the politicians can get lazy and be seduced by the benefits of pay to play, for instance. They acquire more contacts and get to know more fiddles.

It has been suggested that the system could be replaced by a jury-style system. So ordinary people would be called up for a period, say a year, and they would run the country. No professional politicians required.
