Just imagine the following scenario:
The government of country Z has 30 casinos throughout the country, all 30 casinos are owned by the government, in each casino there are 20 employees, that means that the government has to pay salaries to 600 employees, the government will have to give reforms to 600 employees when those employees retire. And also when every high-ranking official of the political party that governs the country wants to play without spending money and put it in the government account he can do it whenever he wants, who will stop him?
Now if the 30 casinos are in the hands of the people and not the government, it will be 600 fewer people that the government will have to spend on salaries and pensions and there will be no corruption from some high-ranking official of the political party that governs the country to play for free
I think you watch movies too much.
In that scenario, the total spending of the government is just a piece of candy for a country that has a healthy industry in gambling. And besides, there's a certain tier where employees will be qualified for retirement benefits. We are not talking about just 10 years of service and I doubt most employees there will remain working for casinos for most of their lifetime.
In the 2nd scenario, what do you mean by if casinos are in the hands of the people? Are there casinos that are run by it? Do you mean private? Then it's not that good for the government as they are just getting taxes here instead of the pure revenue.
What are you trying to point out on your given example? Can you elaborate?
