It was a feature in a time when white men lived, on average, to the ripe old age of 38.
I'm tired of treating anything the founding fathers came up with as sacred. Different time, completely different context. Economics, psychology, and almost all of STEM didn't even exist then. They did not know what they were doing. They got lucky in almost every regard.
Keep in mind in all of human history only about 1/4 of violent revolutions are successful, many that "succeeded" left all parties involved much worse off. America, especially in its inception, was an incredible anomaly that far too many paint as something more in the name of American exceptionalism.
EDIT: Look, our legislature is a complete and abject failure. It's completely gridlocked, arguably by the design of private interests. If it were working to reflect popular interest, I imagine American law and government would look very different. I don't think any of what I'm suggesting here would be even slightly controversial to be quite honest.
