Before Privatisation, BT was a monopoly (excepting a very small, and local company in Hull). A few posts back, you said:
So, how did Public Ownership resolve that, in the decades the monopoly existed?
DB is right in that the regulators *should* play a central part in making sure that markets foster effective competition, but we seem to have been plagued with toothless regulators, who seem to be scared of upsetting the companies they regulate. At least in telecoms, it's very hard to eliminate all competition, as with both cable and mobile networks, there's reasonable choice (when with BT there was none).
I used to work for a farmer who was as true blue as anyone, and I remember his holding forth that he really strongly believed in "the free market with controls". I hated to point out that it wasn't a '
free market' in that case, but I knew what he meant, and think he was probably right for many things.
That said, something like water can never be a free market in any meaningful sense (competition being impossible), and the privatisation was simply a way to try to offload the cost of previous under-inverstment to anyone else but the state.
