You're conflating something being bad by definition, in an inexcusable fashion, with simply not liking it. There's nothing inherently bad about the upper chamber of a bicameral legislature being explicitly not designed to represent individual people in a perfectly proportional manner.

As originally designed, the US is not a nation with a strong central federal government that happens to be made up up 50 weak states and a handful of territories and districts. It's 50 strong states who happen to be united under one central but relatively weak federal government. In that context, having States represented equally, without regard to their populations, makes complete and total sense.

Completely by chance, that happens to indirectly overrepresent people you disagree with. That's unfortunate (depending on your ideology), but it certainly doesn't make the entire system broken or bad.
