I realize that white elephants are a concern, but I Morocco would’ve used the stadiums. I think part of the issue is the insane demands sports federations put on host cities. Huge stadiums are awesome, but not necessarily needed. I also think that joint bids aren’t a bad thing. I think the Olympics and other major events should work on a rotating system. Every Olympiad should be in a different continent, and the countries on that continent are responsible for figuring out a hosting plan, preferably shared between multiple countries, and continents should have the opportunity to skip an Olympiad if they feel unable to host it. But I do agree with many the points you make, especially concerning postering, and I like that LA is currently sports paradise.
