The thing is you can't really say how things are now and transpose them on how things were then. I mean if you cast your mind back to when the web was first taking off, BT were dragging their heels in a big way over the local loop because they had the old public sector mentality still. They enjoyed their monopoly and were loathe to let anyone else have access to it. It was a similar picture with mobile telephony, with the likes of Vodafone and Orange giving BT (Cellnet as it was) a good kicking in mobile. Cellnet and Vodafone were formed around the same time, but where Vodafone had a market cap of over £100bn, O2 was eventually sold to Telefonica for just £18bn, and it was only really after that move that they picked up again.
I don't have efficiency data for the utilities but it wouldn't surprise me to hear the same sort of thing, as there are similar stories from around the world. Venuzuela for instance nationalised (or stole depending how you want to view things) their state controlled industries from the private sector, and the efficiency of those industries is not good. The high energy prices mean they still make reasonable money, but most of that is hived off for other pet projects, meaning those companies are starved of investment.
You could say much the same about the car industry, and both my dad and grandad worked in it so I'm not blind to patriotic allegiances, but the Leyland/MG/Rover factories really weren't up to much, especially compared to the Japanese competitors of the day. It was like a mini (no pun intended) version of what has happened in Detroit. That's not to say the industry is a write off. I mean Toyota has recently expanded its plant, and both theirs and Nissan's UK plants are amongst the best in Europe. We also have a fantastic high performance cottage industry around Weybridge/Woking, with McClaren are the centre. I mean we lead the world in F1 design and manufacture.
Re the job thing, there's an old Chinese saying that I'm going to butcher a bit. It talks about someone trying to build a dam, and due to political inteference they want to employ as many people on the project as possible. So rather than using diggers they employ 100 people with tooth picks instead.
One final thing, you say 'modern day UK' a wealthier place. Lets not confuse the UK government with the UK population. The UK population is considerably better off now than it's ever been. Look on the url below. It shows GDP per capita (in real terms)

It's almost 4 times what it was in the 70's and 80's!! So we're 4 times richer than we were then. Think about that.
