If those who recognized it as part of their culture, it will be good as they can accumulate good
amount of income taxes out from this gambling, if being well-planned and the government is
really serious, then it will be good.
Yes, that's correct. Cockfighting operations as long as it was legal were also complying with taxes. Since the industry is so big, especially in those countries that allow the operation, it's one of the best revenue that a government can rely on.
It's too risky for a politician to operate or influenced an illegal cockfighting operation as to why they should do it if, in the first place, they can just be involved with it legally and have no worries about being hunted down by the authorities.
That's why the government, regardless of the country, is seriously tracking down illegal cockfighting operations so that people will only choose those legal operations over illegal operations where no taxes are being gained.
