Buffy I am comfortably off, but not rich. Work hard and rationed myself to 1 child so as to be able to afford my life.
Ask full employment making munitions, and what about those feckless POW living at the expense of the Germans and Japanese - yes the world was great during the war 
I agree more equal is better than less, but also believe socialism does not work for anyone in the long run.
The current situation is not perfect, but Corbynism would destroy this country, or any country who adopted it, as it did in the 70's and as it has in nearly every country which has tried it.
I have no idea why Sweden and Denmark are successful socialist countries, but it may probably relates to the fact they are very socially and economically liberal, with most taxes being raised and spent locally, rather than centrally. I, personally, have no problem with a Nordic model, but that is not what is being offered.
And it should be noted, in terms of self-interest, very few Labour voters imagine themselves as worse off under a Labour government.
