Except that in housing, water and rail they weren't actually terrible run. And for example in rail they were improving a lot. In terms of telecom the British Telecom had a forward thinking plan to deploy a advanced fiber network.

The question is sometimes, were they terrible run or did they just suffer from bad investment?

Because often they got little money but also had universal service requirements.

Badly privatizing these companies made things worse, not better. Just nationalizing monopolizes is a bad idea, as well as just smashing them into 100s of pieces and leaving behind a mess (see railways).

Also those countries that did things well, see Telecoms in the Nordics, or rail in Switzerland often did it state lead.

And ironically, for example rail required more subsidies after privatization. While also losing the amazing research and forward thinking organization that was British Rail.

I would argue improving these national industries would have been far easier and more successful then privatizing them. And ironically often cheaper.
