Congress can’t do anything because of the filibuster, two party system, and republicans though. The whole thing honestly needs an overhaul.
You can wait out a filibuster. You just don’t allow new business until they’re done. That means they have to keep talking and eventually they’ll run out of speaking ability.
A filibuster raises the vote threshold, so it’s not something you can just wait out. And thank to how the filibusterer works nowadays, congressmen don’t actually need to get up there and talk, they can merely threaten to filibuster to raise the vote threshold.

What do you think a filibuster is? It’s an active debate. So yes, you can wait one out. If they can’t continue, then their time is over and you vote. It’s why they’ll get up and read books.
To break it, you don’t move on to new topics until they give up.
The Senate not being population-based is part of the problem too. As are gerrymandering and not having universal adult suffrage or federal holidays for voting days. But a Constitutional Convention would be state-based, too, so we’d end up with something even worse than we have now.
