In another unrelated article I saw a map projecting mega cities in the USA. One surprised me intensely, they were projecting one to grow starting somewhere up around Central Michigan , south and East towards Cleveland Ohio, spreading down across much of the East 1/2 of the state state then towards Cincinnati. From there one little finger stretched out and connected with louisville where it ended. Another odd finger stretches SW and connects to St Louis. Truly huge. All this talk about population collapse I think is silly. Even though some of it comes from Jordan Paterson who I greatly admire in most subjects. The 3rd world nations populations are still exploding and this new no border nation we live in assures they will move here and more than make up for the low birth rates.
