Here I would like to intercede as a person who knows a little | WORLD_IN_FIRE

Here I would like to intercede as a person who knows a little about the problem of gambling addiction in China (and not only there, gambling addiction is a cultural Asian feature) and the reasons for the introduction of this policy *. For reference - they started talking about her at least two years before the appointment of Chairman Xi.

To begin with, extrapolating 15 percent to a billion and a half will bring us to a figure of 225 million people - this is practically the entire population of the United States, if we draw analogies.
Secondly, gambling addiction in China is a very multifaceted phenomenon, which, among other things, does not allow Chinese citizens to enter the Macau SAR on a tourist visa more than once every 2 months. State officials and other equated persons are generally deprived of the right to enter (and in Macau itself, SAR officials have the right to visit casinos only for the first three days of New Year's holidays). At the same time, Macau casinos are almost entirely dependent on tourism from the mainland, and in 2018, it seems, their revenues were seven times higher than the revenues of Las Vegas open to the whole world. This is why concessionaires like Sands and Wynn stay there, even though they pay 53% in income tax.

Thirdly, as the experts who promoted these decisions (they were not taken at random) say, they have one and a half billion in their country and the various consequences of gambling addiction have a slightly different impact on society, which will be in a country with a population slightly more than the number of inhabitants of the province. Guangdong (113.5 million), or even many times less.
And finally, I would like to note that the lies when testing for addiction is connected, among other things, with the fact that addicts involuntarily seek an excuse for themselves and their behavior. And they realize it, by the way. Therefore, you need to look at the polls, their wording and, based on, add a corrective percentage.
Well, there are many, many more subtleties and points in the problem of teenage gambling addiction. Therefore, it is too early to judge the effect of measures when they are just taken.

* I recommend that you familiarize yourself with the national legislation of Singapore on citizens' access to local casinos.
