I would love to test all your hypotheses, I'm skeptical. My
impression is that, even if you compare dense high-income areas (Manhattan, SFBay), many other countries are still coming out on top. For instance, Warsaw (!) metro area: 631.4/km2, Manhattan: 27,227.1/km2. I don't have the numbers but income is much higher in Manhattan.
Wikipedia tells me I can get 60mbit/s down for under 25 USD in Warsaw and I think that is uncapped. I don't believe any comparable deal exists for Manhattan. SFBay is similar.
