Nice review--thanks, as always! Just to flesh out a couple points (since he was the single politician I paid any attention to, so I heard a number of long interviews he gave):

So what Yang proposes, basically, is an economic safety net that is automatically and immediately available to every single human being in the United States. At least, I presume so as he never talks about immigration at all.

His policy proposal was actually limited to US citizens 18 and over. When asked about it, he gave one of his worst answers I heard him give to any question, which was basically "mumble, mumble, fairness." It was obvious that he thought that every legal permanent resident in America should be eligible, but that his political staff convinced him to say "citizens" for the same reason you cite that changed to "freedom dividend". Personally, "freedom" aside, I think calling it a dividend is not just smart but semantically correct, if you believe we're all shareholders in America (a la popular sovereignty) and therefore should have some reward when America experiences a profit glut as we have for decades now.

Second:

I still don't think he wanted to be president in 2020. I think he's got a much better grasp of the kabuki than I was giving him credit for. I think he ran for president in order to increase his access to other policy people. I think he's building a coalition for 2028.

He was the only candidate I've ever heard say "yes" when asked if he would accept a VP or a cabinet position were he not elected the nominee. The standard line is always supposed to be, "I'm focused on this race." He was very willing to all but admit that he was campaigning for secretary of something (treasury? labor? some new cabinet department?). I really respected that answer, because it was so honest.

I also really appreciated the fact he almost always answered the question that was asked of him and did so as completely as he could, which is another non-politician move--no pivoting to the message you want to get out. I think the moment I became a Yang convert was when he cited the stat that more people are currently on disability than are actively looking for jobs (obviously not true anymore! but it will be again soon), then went on to try to say something smart about how to address that. He also wants to vastly reorganize the way we collect taxes, which to me is a game changer. I hope he's around a while. I very much regret not getting a chance to vote for him.
