Where have all the senators gone?

I mean the real senators as we have known them in the past, who lived up to the etymology of the term (from Latin senex, old man), and who embodied the ancient tradition of the Council of Elders of selfless people who had no other interest or motive but to share their wisdom accumulated over decades to ensure the welfare of their community.

Compared to our senators now, the time of real senators even seems to be a mythical age of political titans.
