The Olympics really are a terrible waste of effort and resources for the host nation, and the host nation rarely, if ever, gets a positive return on it. Mostly, it seems only to serve to increase the prestige of some head-of-state, nothing more. In reality, it costs an enormous amount of money to build facilities that are only used once and then go to waste. The world would be better off designating two separate, permanent Olympics facilities, one for summer and one for winter, and just reusing those every 4 years.

If we held it in Athens (not sure if Olympia could support it?) for the summer, then have it rotate between countries that can host without massive infrastructure changes for the winter (NA - Calgary/Lake Placid, Europe - St. Moritz, Oslo Asia - Beijing, Pyeongchang).
