Gerrymandering (on any side) isn't going to decrease unless the federal government begins enforcing it under Constitutional and civil rights law, with Supreme Court blessing.

Among its many flaws, the Constitution should have had a "elections run by an objectively fair method to each citizen" caveat before giving states the right to run their own elections.

But that would have been pretty progressive for the late 18th century...

In my dream world, we'd put enforceable boundaries on how much gerrymandering is acceptable via statistically stable methods (e.g. efficiency gap calculations).

The easier solution would have been parliamentary-style proportional party list representation, but I'm not sure the fairness benefits outweigh the "not being able to vote for your individual" drawbacks.
