The point of the Senate was to get states to ratify the constitution. That’s it. Smaller states didn’t want to agree to join a union where they gave up power to a federal government dominated by the larger states.

The Senate should really be abolished, and the # of representatives should be doubled to temper the impacts of gerrymandering. If smaller states want more power against larger states, they can work together with other smaller states to form a voting bloc in the house.
