As another comment said before, travel nowadays tends to become that super selfish adventure where the only things that matter is to come back with the best selfies and brag on social networks about how cool it all was. It is not like that for everyone of course, but I have the feeling for a lot of people traveling means going to somewhere famous to get a stupid Instagram shot, with zero concerns for other people or the environment.
Maybe that like everything else, traveling became too easy which started a race to the bottom for attention and pushing people to do more and more stupid and selfish things to be seen.
