Note that constituents in the U.S. have the worst representation of any OECD country. Worse than Commie China. America's biggest problem is the "Permanent" Apportionment Act of 1929.
I would go even further: maybe congress should be expanded such that we have different chambers for different aspects of life. This way we could elect a lawmaker for each domain... e.g. 1 focused on environmental legislation, 1 focused on financial legislation, etc... rather than trying to cram all sides into a single unicorn lawmaker.
I mean it's not really going to do this in practice, because Congress can and will continue to be dysfunctional it just means that the court rather than the agency is going to make the call on what the law means. Without a way for the judiciary to be say, "this law is too ambiguous to rule on, Congress must pass a law right now clarifying their intent, then we will issue a ruling" it's just going to be the judges making a call.
