Minor correction: the Senate is 2 per state, so Wyoming’s 1 state has the same representation as California’s 1 state. The Senate is (supposed to be) the voice of the States in the Federal Government. The Senate wasn’t even supposed to be elected by popular vote, they were appointed/elected by their state governments until the 17th amendment. The change made senators into super-representatives, which changed power dynamics. Arguments can be made here for whether this was ultimately better or worse.
The House of Representatives IS the voice of the people, and should be proportional to population size (but was artificially capped because the Feds complained it was getting too big so now Wyoming has more representational power per person than California). This needs to change because it’s only going to get worse going forward.
With this breakdown, the Federal Government’s interests, State’s interests, and the People’s interests balance each other. These three bodies have vastly different focuses.
