It's not example of poorly designed privatisation at all, in fact its an example of how it supposed to work. If the market demands it then it would be supplied, but the margins are so tight, that while in your area people will pay for leased lines then why would they put FTTC in ??? I suspect in your exchange area it just doesn't make business sense to put it in.

You can pay for Openreach to put fibre in, there are loads of Ethernet Fibre products delivered through all sorts of SP's out there. And the cost is reflected in the service offered.
