I mean, I'm not saying it's the best system, but "one Chamber gets the same for all states, one Chamber is based on population, & they have to agree" is a decent idea. Granted the House is no longer proportional to population, but the *idea* can't really be faulted when you're a bunch of 18th century rubes with no internet & conflicting views trying to invent a new system of government from scratch. Flawed, absolutely, but not a terrible proposal on its face.
We shouldn't worship them, as many in this country do, but we should forgive them for not being perfect. The real problem is that it's SO intrinsic it'd be impossible to change short of Civil War 2.0, which honestly no one really wants, even those who might advocate for it while in their AC homes typing on their iPad with grocery stores & McDonalds/Walmart right around the corner.
