1. Support from the government.
Countries who gamble a lot has solid laws protecting their players so gamblers in those countries can just freely gamble as much as they want without having to worry about their rights.
This doesn't mean that the countries have very free and loose rules but it just means that they have clear frameworks. Some other countries have some limitations but since their rules are clear, many still gamble.
I understand your point or the angle you are driving at, although it may be true that most countries that have laws
Protecting their
ppl players to Gamble in those area
, but does
givennot gives them the privilege to gamble above other countries. Don't be even surprised that a country that has a regulation that prohibits it's citizens from gambling may even be higher in population when it comes to Gambling. You never can tell though but you are just guesting without a real fact. It's just like saying that those that are rich can gamble as they like because they have the money, without knowing that a poor person may even gamble higher than a rich man because he want to make money by all means and doesn't care how much he is able to spend to make the money. While in other hands the rich may be very careful not to lose his wealth to Gambling and or betting.
