Originally:
representatives were about 2 1/2 times in number as senators (65 vs 26).
Now:
there are 435 representatives vs 100 senators, or about 4 1/2 times in number;
the 2 1/2 to 1 ratio would translate to 250 members in the house of representatives.
Originally:
representatives were 1 per 30,000 in population.
Now:
that would require 10,000 members in the house of representatives.
Could you imagine 10,000 members of Congress?
All of them with high priced benefits and staff. It’d be insane.
I'm not sure having such a large body would be a bad thing. It would make it easier to hold them to account, as well as making it harder [or at least more expensive] to buy favor.
