In other places on earth, selling public utility requires the company to operate at similar or better level of services previously provided while retaining the cost. And those deals are mostly regulated, penalties when not meeting them.
And it used to be, may be in rare cases the people in Government making those deals actually knows what they are getting out of it, so the contract are all well written.
Now it seems they are selling because 1. They dont have money. 2. They are running it poorly. 3. They are bribed or have incentives to sell it. All with no caring of how the people they serve were getting any good value out of it.
