I disagree. Fundamentally we have the final authority to elect our representation. Collectively we decide (and are ultimately responsible for) who is elected to office. Districts don’t vote, and corporations don’t vote. The people do.
It is the collective responsibility of those not disenfranchised or otherwise excluded from the political system to rectify those problems. Failing to address those problems (or any political problem) isn’t a failure of the politicians–it’s a failure of us, as a collective, to choose the appropriate lawmakers. Especially when we repeatedly elect the same people over and over.
I know it sounds naive to frame the system this way. But fundamentally the political system operates under the collective authority of voters.
