There are a lot of issues in the American political system but the structure of the Senate is not one of those.

It was explicitly created as a way to balance sovereignty of the states against populism, such as that enacted by MAGA or leftists.

If you are a small state like Vermont, you don’t want to just have California, New York, and Texas dictating all rules and laws for the country by sheer weight of their population sizes. That is expressed in the House, but the Senate serves to balance that and ensure that populists don’t run roughshod over the country.

Without such a structure states with less population would either band together and create their own super states - and you can see where this leads, or they wouldn’t have agreed to join the US in the first place.

This might have made sense for the original 13 colonies but after westward expansion, it clearly does not. Most of the western state borders were formed for administrative reasons

Yet that is exactly what has been happening twice now.

Yes, if anything the issue is that the House was capped in seats in 1929 and the population has tripled. Smaller states have an outsized representation in Congress currently.
