In the context of discussing a company that lets employees work remotely, it is precisely as high-on-the-hog as $150k in KC. Remote employees in NYC choose to live there, because they think it’s a good tradeoff. If employees A and B both make $150k in Kansas City, but A cooks all his meals and B goes out to eat all the time, that doesn’t make A high-on-the-hog and B middle class; it just means that they value different things. Ditto for remote workers who choose to live in NYC.
