Hacker News cannot solve all the world's problems. Not even all the problems related to technology. It's ok to focus on the things we can do effectively. HN isn't the only forum to discuss important issues.
I can't say I know what that is, but are you sure about this? The HN community is overwhelmingly not in California, and comments about California seem to me to skew to the critical and negative.
There's a lot of different people on HN. I don't mean to say we're all the same. It's just that voting is a low-pass filter.
