While I know your point was relating to points, the overall volume of people of travelling internationally is only going to continue to go up as more and more of the world's population (which is also increasing) is becoming affluent enough to travel internationally.
It is one reason why my wife and I now tend to favour travelling to places off the beaten path as places like major cities, or well known sites/attractions are just swarming with tourists and queues. Apart from the swarm, what is then at that site/location is often a an ersatz experience. Sure we still visit major locations, but after each trip what we have most enjoyed enjoyed is always the lesser known locations and activities.
My wife and are just back from walking 400km through mainly Tuscany on the Via Francigena. We walked from hilltop village/town to hilltop village town. The "tourist" meccas like Siena and San Gimignano we overnighted at along the walk were just zoo's during the day. Whereas, there were many amazing villages we stopped at which where fabulous and largely deserted of travellers. There are just so many hilltop villages in Italy that most are just not visited much. Sometimes just as they say lack a good rail connection.
The dining was authentic, and much cheaper too and when dining rather than being just part of an international throng, we were often the only non-Italians there. Whereas is say Rome or Siena if you go to a restaurant you will mainly just be given the English tourist menu, rather thana menu based on what local seasonal produce is best at that time.
