I do not think that the French authorities should be proud of the increase in tax collections received from the gambling sector, coming to the treasury from the pockets of their own citizens. They become poorer exactly as much as the state becomes richer. In my opinion, we can be proud of some upgrades in production, an increase in revenues to the country's budget from external sources, but not from the pockets of our own citizens, especially at the height of the pandemic when people are forced to spend more time at home.
I do not think that France is proud of such tax revenues. However, taxes are taxes. If people want to gamble, they will still play them. So let them play in French casinos and bring taxes to their country, than they will bring taxes to other countries.
