That's a competition problem. If its a monopoly and you just change the owner you are not solving anything. The state job must be guarantee the competition, not to run all kind of business.

With the levels of corruption, unemployment and nepotism in Spain the less state the better., They want to run state owned business to give jobs to his familys, friends and politics. All state owned business here give really bad service and they lost hundreds of millions every year that are paid by all taxpayers, not just the users.
