Up here in Canada, the government does own businesses, directly and through "Crown Corporations". Some have a monopoly and some compete with private industry. The government owns the postal service ( Canada Post), power companies ( i.e. Ontario Hydro), airlines ( Air Canada ) and, the biggest cash cows of all, the Lotteries ( dozens of them) and Booze distribution ( i.e. the LLBO).
Most of these companies are bloated disasters. Air Canada, which is touted as a great success, has actually gone "bankrupt" notwithstanding getting all the best routes and facilities. And the no brainer monopolies like Booze could be outperformed by an outfit run by the Three Stooges.
Government is not very good at running or creating businesses. The better idea (usually) is to let private business compete to maximize efficiency and revenue through market forces so that the government can tax them
without the costs and inefficiency of running them.
The government has more than enough money to do what it is supposed to do. It should learn to live within its means and get out of the way of those who actually produce wealth and create jobs. Fat chance.
