This is a relatively easy, relatively bi-partisan issue that can be handled quickly. The other issues you mentioned cannot be described that way. It's an equal opportunity annoyer this commercial volume problem.
I agree with the monopolies issue, although it's not government imposed, it's media-industry lobbied and government permitted. Notwithstanding that, we can't all afford to go out and buy those TVs that modulate the noise for us. It's not always convenient to get to the mute button, and some of us are sensitive to disruptive environmental things and can be very overwhelmed by the screaming commercials.
And I will gladly send a buck to everyone to votes for it. I'd send more, but I can't afford it.
I have the right to watch my TV without being assaulted, without having to worry about muting the TV when I'm busy with something else, and without having to worry that my neighbors are going to start pounding on my walls/floor/ceiling because the commercials are insanely, ridiculously, unnecessarily loud.
Sure, it would be preferable if the morons responsible for this brilliant industry tactic would police it themselves, or simply get a clue, but they won't and they haven't, so let me take this opportunity to help these people out.
WHEN YOU BLAST YOUR COMMERCIALS SO THAT YOU CAN MAKE SURE I HEAR THEM WHILE I'M ON THE CAN OR GRABBING A SOOTHING BEVERAGE, I MUTE YOU INSTEAD OF LISTENING TO YOU. YOUR TACTIC IS BACKFIRING. SORRY ABOUT THE YELLING BUT...WELL...YOU HAD IT COMING.
