That was literally the first links of dozens. I can pull articles from NYT, Crain's, CNBC, you name it, all showing the trend. The budget deficit alone should suffice. The fact that you ascribe a "political agenda" and use the phrase "show your ass" - what is this supposed to mean, that we discovered the enemy in the room? Don't answer that, I don't want to know.
I don't want dozens of links to Crain's. I want primary data that shows the current net domestic migration out of New York (or SF, you pick) is unprecedented in decades, which is what you said.
