NONE, NADA, NICHTS
Since the bad decisions made at the end of Prohibition, no state has ever shifted from a private free market system to a state-run liquor monopoly. Not once, not ever.
Our system is so good that nobody wants it. No one else believes in it except Utah, the only other state that is like us. Even they are somewhat better off since you can buy beer in grocery stores there! Alabama is looking to change, Montgomery County in Maryland, a "control county," has passed a partial privatization this year, Literally hundreds of towns in Texas alone have "gone wet" and even some here in PA, like Antrim Township.
The truth is that most people do not want to live under the quasi-prohibition model of the PLCB, be they in Pennsylvania or even under the more liberal versions found elsewhere. People want to be able to choose what they want and not what some bureaucrat in the capitol decides they should be allowed to have.
We don't want the corruption monopoly brings, either. Graft and corruption is not limited to the PLCB. North Carloina has its share too. Even 40 years ago there were charges and nothing really has changed since then. PA is no different. 5 senior members charged with graft, longstanding nepotism, junkets and "tastings" for members that have no qualifications to select mouthwash let alone wine for the entire state.
Painting the PA liquor jail cell a nice bright color, putting up new drapes, and calling it "modernization" will not change the way the system works. The state charging more is no better than anybody else charging more, except that in a free market you can shop somewhere else. You don't have that choice in PA; it's the State Stores...or the State Police.
The State Store System does nothing for the citizens. It limits job creation, tax collection, selection, service, choice, and entrepreneurial drive of small businesses. I think we can do far better: don't you?
END IT, DON'T MEND IT!
