You gotta return to your grade-school history textbooks, my friend. You can even read what the Framers wrote as they debated, at length, this very topic. It was the major sticking point between the populous states and the less populous states, and the bicameral legislature was the compromise.
Either way, I'm not concerned. You'll never get enough states to give up their representation so it'll never happen.
I'm not saying you're wrong about how originally only white male landowners were able to vote. But... That's completely irrelevant to the issue of apportioning representation. The bicameral legislature provides fair representation to every state, whether it's big or small. I don't see how that could be anything but beneficial to everyone, whether they be a white male landowner in California or a black female renter in Rhode Island.
Anyway, you aren't going to convince me that your folly is the best course for this nation. I'm not too concerned because, like I said, you'll never get enough states to go along with such a horrible plan to replace the Constitution.
Good day.
