All is not well in the world of Reform

Sorry I dont go back as far a “Super Mac”,

Good Lord, David. I thought the 49 in your username was your birth year. It can't be if you don't go back as far as Super Mac.

to me a mixed economy is a balance of service and manufacturing

I've only ever seen the term used very specifically to describe the mix of private and public sector provision of goods and services consequent on Labour's nationalisation programme post WW2.

A mix which tory governments seemingly concurred with (so PMs Eden, MacMillan, Douglas Home, Heath, have I missed any?) until Thatcher arrived with the wrecking ball in 1979. And the insistence that the UK could do absolutely fine without any heavy industry because our financial services sector was gong to provide all the jobs and income we needed.

It worked pretty well on the whole and I would very much like to return to a better mix of public and private provision.

Vintage 49 for sure, in my school days the biggest memory of Macmillan I have is the Christine Keeler affair and all the schoolboy sniggering about that.
The height of the Cold War, Kennedy dead, Mao exterminating millions in China, Vietnam war raging, UK politics was pretty tame by comparison

Sterling exchange rate was around £2.50, it’s been all downhill since then, “You’ve never had it so good” was the Tory opinion.
Then Wilson was elected, inflation reached 25%, interest rates 16%. The only bright spot since then was North Sea Oil that offset the damage Thatcher did.

So I do have a fondness for the old system not the economy we have today
