In a truly representative republic which reflected the intent of the Founders, America would have 100 senators picked by the state legislatures, not by popular vote, and at least 6,561 members of the US House (using the ratio of 1 representative per 50,000 of population intended by Article the First, not ratified; the father of our country wanted a ratio of 1:30,000 for 10,934 members of the US House in 2018). Instead we have 100 senators and 435 representatives, and 10,840 lobbyists in 2018. The corporate takeover of the Congress was a fait accompli by 1929, thanks to Republicans.
The English today are better represented than Americans with one member of parliament to about 101,000 of population, for all the good it does them. In the US the current ratio is 1:754,092. When Republicans stopped the growth of representation once and for all in 1929, the ratio stood at about 1:280,460. Using the 1929 ratio in 2018 would mean 1,170 members in the US House instead of 435.
Surely what was good enough for 1929 is good enough for 2018, no? But good luck even with that.
