So many countries economy are down now, and they need to rebuild their economy after the pandemic, inflation and unemployment are on all-time high now, do you think the governments will supports, give licensed and allow more gambling casinos and online casinos so they can recover their economy coming from gambling revenues, and can this revive the economy of one's country.
Their is an anti-globalization movement going around the world. Every country wants to be self sustainable and this would bring a decrement in the foreign cash reserve for every country. And gambling is a easier way of bringing foreign reserve for many countries. So, I believe most of the countries would make it easier for foreigner to come and bring money to gamble. Economic crisis would mostly affect the mid-level people increasing the gini coefficient so I don't see the number of gamblers decreased.
From my own observations, it is in my opinion again, that most if not all of the people around the world are going back to "tradition" and is fighting the far left and fighting globalization to the point that some of these governments are trying to separate themselves from the mainstream west and more of wanting to be on their own. They know that over dependence with the US dollar will bring big consequences in case the U.S. itself is in a state of disarray. Anyway we can be sure that with increased separation from the west, a new paradigm will occur and nations will be self sufficient. Gambling at that point will be "localized" putting empasis on local participation of the people in small town gambling and the casinos will concentrate on areas with big population.
