the problem is that since 1911 the house has also been a compromise for smaller states to have leverage because it's capped at 435 total members regardless of population. we've gone from a system of dynamic tension between popular rule and representation for smaller populaces to a system where both houses are on the side of the "underrepresented" to an extent where they're actually vastly overrepresented. Combine that with the electoral college (which again allows a ruling elite to overrule the populace and advantages smaller states) and the fact that the elitist president and elitist senate pick the supreme court and you can see where the so-called "underrepresented" populations are actually the ones in charge of every branch of government.

This is, of course, exactly what the founding fathers intended. They disliked kings but they feared rule by common people and always intended there to be a privileged class of citizenry that does the actual ruling because people like you and me are just too ignorant to be trusted with that. That's why they excluded the vast majority of people from voting at all and those that were allowed to vote had their power diluted by various mechanistic means like capping the senate, flooring the house (and later capping it as well), using the electoral college to make sure that those precious few who vote at all don't vote incorrectly and having the least representative members of the executive and legislative branch select the judicial branch so that they're not swayed by "politics" (read: what the governed actually want).

And that's how we have a system that claims to be a democracy but where what people want is actually completely disconnected from what happens, and where "The opinions of 90% of Americans have essentially no impact at all" (https://act.represent.us/sign/problempoll-fba/).
