There are always improvements that can be made to the system, but I think the end result is inevitable: democracies and republics inevitably end up being controlled by the very rich. Think Roman Republic and the first Triumvirate. This is nothing new, the American system is a vast improvement on the Roman one and the outcome is the same. It kinda starts to sound like "well that wasn't real communism."

"that wasn't real democracy"

"we coulda designed a better constitution"

c'mon
