One part of the 18th century that we left behind that maybe we shouldn't have was the level of representation in the house. Back then, each US rep had about 10,000 constituents, but today each has close to 1,000,000.
Going back to the original proportions, and having ~35,000 representatives could solve a lot of the money in politics issues.
