People do try to measure this stuff.
Now, that does open the door for people to game the system, but you can’t simply define all lobbing as corruption or even all lobbing you disagree with as corruption.
So, yes their are plenty of blatant cases of corruption but they are relatively rare compared to China.
Compare: "China is actually not inherently undemocratic there's a lot of local officials etc being voted in".
Yes, but on the systemic, overall, scale there's a blatant democratic deficit present for all to see.
Now, is politics in the US rigged? Ehh. You do need to actually participate to be counted. Don't vote and don't lobby then sure they your voice is not heard. Now does everyone get equally rewarded when they vote or lobby? Clearly not as every vote is not equal and frankly that's part of our constitution. So is the US a democracy? Nope.
On the other hand the US is not a totalitarian state, the will of the people does actually matter and things happen without bribes every day. Compare it to say England where the landed gentry got to hold extra special power rather than ever shifting groups in the US and yea it's not that bad.

7. Puerto Rico still isn't a state.
8. Two out of the three heads of state this millennia won election after losing the popular vote to their opponent.
As an American, we certainly aren't civilized.
