Exactly right. Of course this was back in the day when the term "representative" actually had meaning.
Do they need to be in Washington?
They all gathered in one place because there was no alternative at the time; no telegraph, no phones, no instant means of communication. It's absurd that they all have to gather at the temple these days.
They can work part-time from home which is reasonable with only 30,000 people to answer to. Also, imagine how response they'd be if they acutally had to live, work, shop, attend ballgames, church, etc. with the people they represented.
No kidding. Imagine their horror at having to actually interact with the great unwashed at the coffee shop. They'd all be stricken with agoraphobia.
Also, while there will always be plenty of money to buy votes, just imagine the logistics involved in paying off 1000, 2000 or 5001 critters. The paperwork involved. The travel.
Bingo. After all, People for the Ethical Treatment of Insects and the The Coalition for Living in Cold, Dark, Unheated Caves only have so much money to throw around.
Our betters will never allow this as the present system affords so many . . . perks. I like the way you think!
