I do hope you were joking about only union people being able to handle such a responsibility as the sale of alcohol. And of course government intervention in anything just raises the price of everything involved - so any profit from the stores is probably being eaten up by the cost of union employees.
Yes, it is legal for bars to sell six packs to go. (But no more than two to any one person.)
And yes, I was being snide about the massive training and unionized expertise required.
But, the state store system does make a profit for the state. it contributes revenue to the treasury. Over and above the taxes on liquor that would remain under a private system.
I would need to see a good plan on how to replace that revenue stream, and have some politicians that were trustworthy before I would approve of any privatization. Change just for philosophical reasons is not good enough.
