Dear Fred,
No system can be perfect. But a system can be considered to be closest to ideal when there is least chance for error (going astray) and when it is practicable. Members within the elected house when they are not bound to political parties and when they are constantly watched by the people who elected them (and recalled if needed) and where they have to use all their positive qualities to fulfil the job for which they were elected, are most likely to obey their conscience. Simply because the conditions are favourable for only such a course of action. Thus the system taps the best out of human nature.
