Being British, I grew up with a state-owned telephone monopoly, a state-owned railway in British Rail, cars built by state-owned companies, and state-owned media and healthcare that continues to this day, all of which are or were the worst in the developed world. My parents grew up with state-owned holiday companies, state-owned road haulage companies, a state monopoly on all broadcasting that lasted until 1973, state-owned airlines and far more besides.
I could make a long, boring post about how state monopoly ownership of industry results in the worst quality imaginable and no way to access alternatives, but I will not because I have just had a vision of what state-owned pornography from the people who brought you the British Rail Sandwich would look like and I have to run off and be violently sick.
