Ah yes, because our healthcare system has worked consistently brilliantly over the past few decades.
One of the major institutional problems of our healthcare system has been a lack of attention to preventative medicine and another has been a disconnect between health and social care. With all his faults (and undoubtedly any healthcare system would develop problems over time) Morrison's preferred approach was at least slightly more holistic than the one we took OTL, it might also have reduced the post 1945 erosion of civic pride and drift to centralisation of services.
Morrison pursued a compromised managerialism in public ownership, accepted massive cuts to welfare to fund foreign wars, literally wanted to build a ‘British African Army’, and organised the 1953 coup plot against Mossadegh (Eden just dusted off the documents from Morrison’s time in office). He was a petty imperialist with a vindictive streak who wanted councillors in control of everything because municipal leaders were his base and he controlled all the ones in London.
I did acknowledge that he wasn't a nice man but you will have seen my points above about the health service and indeed about local government generally. A British African Army sounds bad to our modern sensibilities but the UK didn't decolonise Africa until after Morrison had left politics. He stood down in 1955 OTL and African decolonisation took place 1957-1966 with the modal year 1960. Assuming Britain is going to maintain a military presence in Africa for the next twenty years, a British African Army is arguably a cheaper way of doing it than the more piecemeal arrangements of OTL and might just have butterflied away Idi Amin Dada and some of the more unpleasant Nigerian generals of the 1960s and 1970s.
Arranging a coup against Mossadeqh? Not very nice behaviour but rather typical of the time period. Leaving aside the USSR land grabbing and sponsoring Communist coups in Eastern Europe, we have the USA in Central and South America, France in Indochina (and later France in the French African Community- Bob Denard was of course a mercenary with no connection to the government of the Republic. None whatsoever. Absolutely none). And even OTL Attlee's determination to get out of India quickly and to screw over Pakistan to India's advantage cost hundreds of thousands of lives. Not to mention the SIS with the acquiescence of Ernie Bevan sabotaging shiploads of Jewish refugees heading for Palestine.
Something of a bully, yes potentially damaging. In my view Labour is still recovering from Gordon Brown's intolerance of opposition.
Acceptance of welfare cuts, not good but Morrison was also less economically naive than the majority of his Cabinet colleagues who thought that, after an initial surge, spending on the NHS and welfare system would start to fall.
Morrison interests me because his municipal model is a departure from the standard approach of state capitalism and would have marshalled the significant state intervention in the economy, health and welfare systems rather differently to OTL. Bevin, Bevan, Cripps or Greenwood would have essentially followed the Attlee model to a greater or lesser degree. You need to go to Morrison (municipal socialism) or A V Alexander (co-operatives and beginnings of industrial democracy) if you want to actually see a significantly different model of socialism to OTL.
