> it's the people's house

You dropped an adjective: wealthy

No, the Senate, Presidency, and Legislative branches are for the wealthy. The constitution was literally written so a minority of rich people would have the most control over the government. Having state legislatures (who also happened to decide who can vote + how) choose senators, requiring the senate to pass bills written by the house, judges that are chosen by senators. House of reps only serve for 2 years compared to 6 or 4 or lifetime appointments.

The 17th amendment is a little over 100 years old.

People need to stop treating the US constitution as this "mythical" thing rather than the reality of it being a very undemocratic document that is highly resistant to change.

Luckily the house can be expanded with a simple majority IN the house, one way to truly combat this.
