One is our increasing indulgence in irrationality, to the extent that we almost celebrate it. I would never have guessed that hard-right social conservatism would still be a dominant force in American politics, much less a booming business. So I got that wrong, and I'm willing to admit that happened because I didn't take the time to understand those who thought differently from myself, or how their social motivations, family backgrounds, and economic pressures are different from my own. So, my bad.
The other is the continuing notion that it's somehow desirable, much less necessary, to cram everyone into a few high-density cities on either coast. From a 1990s perspective, it appeared that the growing availability of fast Internet connections and the rise of online social, technical, and business networking resources was finally going to liberate us from crowded, noisy, polluted urban prisons with endless traffic jams, out-of-control taxes, and multi-kilobuck rents.
It should have become both possible and desirable to do anything from anywhere, from the middle of flyover territory to the north coast of Alaska to the freaking International Space Station. Instead, we just get more of the same complaints. Rent is too damn high, there's too much traffic, and man, San Francisco/Seattle/Austin/New York used to be cool until all these techies/hippies/yuppies/homeless people/Republicans showed up and ruined it.
I'm not willing to concede that my worldview is wrong about this. This time, it's everyone else who's being stupid and needs to get a clue.
Just leave.
