Philippine President Duterte suspended the operation of the government-run lottery because it is spam infested and many governments appointed officials are pocketing money coming from the sales, do you think it is much better to let a private company run the Lottery or they set up a monitoring board to check if all funds are all remitted..

If a private company were to control the lotto industry, expect people to sway and deviate from this practice. The reason on why the government controls this type of gambling (although it has been branded as a corrupt system), they still have the power, authority, duty, and goal for the protection of its individuals in the society. Having to be controlled by a third-party would mean that it will be a LARGE-SCALE gambling for all people that derives it profit from a fraction of what people bet.
I doubt that a private company would even attempt to do this as people may get easily scammed from this scheme.
