"People don't care enough about my pet issue" does not make politics broken for any value of pet issue no matter how legitimate said value is.

"Politics is broken" is right up there with the. "people are bad at X" family infantile assertions always boil down to the old Principal Skinner "everyone else is wrong and I'm right" argument. Said argument is inherently wrong for issues of social norms or consensus where the "average man" is always tautologically correct.
