It might also make it easier to corrupt members. There are currently about 710,000 people in the average House district—big enough that no one interest or faction can dominate everybody else. But the more we shrink each district, the more likely it is that one group—maybe a company with many employees or a particular religious sect—makes up a majority, meaning that the representative effectively works for them rather than the public at large.
So imagine a larger House of Representatives—more chaotic and filled with shady characters. The other branches of government—the Senate, the president, and the Supreme Court—are not going to want anything to do with such an unreliable partner. Instead, they’ll do everything they can to strip power from the House.
Expanding the size of the House, far from making the chamber more fair and effective, would make it less so.
