It's two fold but I think the government of Thailand wanted to attract high rollers in their country to play and so they will benefit not just from tourist but from this high rollers as well. And with that it could mean more jobs as well to the local people. Second is the tax that it will generate for them, almost half a billion dollar according to them.
Not only high rollers but also huge gambling investors. The article also calculated the possible coming investment on the gambling industry when they legalized it. The development of a gambling hub, and gambling infrastructures will surely give more jobs to Thai citizens. And the uncollected tax from illegal gambling activities will be minimized. The government will also get fund from the gambling license request and other needed documents fees.
If Thai government thinks that they can gets addictional income from the gambling taxes, that will be good solution for their country because gambling revenue is big so the incoming taxes from the gambling industry will also big. Rather than to prohibit gambling, the government can makes regulation to control gambling plus they can gets additional income from the taxes.
Lol to the bolded part. I think gambling addiction is already a problem of any country including the Thailand government. At least with the implementation of legal gambling, the government can have additional funds to utilize some of the government branches to disseminate information about minimizing gambling addiction.
But the government needs to discuss with all elements on their country because there will be a pro and contra with that regulation. That needs to be clear so when the government legalize gambling, no one will demo the regulation because that is for their country. Their people will be happy if gambling can be legalize, especially traditional gambling because we know many Thai people still playing gambling using the traditional gambling games.
I bet the only group that will go against the legalization of gambling in Thailand are those close-minded religious groups and/or those who run illegal gambling. The citizen who are already engaged with gambling will be happy knowing that they are not committing a crime anymore when engaging in gambling if the legalization of gambling is aprroved.
