I don’t see any logic behind giving every state equal representation when each state is not equal in population, commerce, or even territory.

I think the need for both a senate and a house is important, and the distinction between the two would be that individual districts select the house appointments while the state as a whole decides the senators.

I think the additional chamber of the senate helps quality control over changes by the house, and makes it harder for harmful changes like those by the GOP to pass while incentivizing changes popular by the larger majority.
