This conversation seems to be going round in circles, with anyone suggesting that wealth should be more evenly distributed being accused of jealousy and/or wanting some sort of revolution, and those who believe in market forces being accused of not caring about others. Probably neither group is saying what they are being accused of.
I think that it would be better for society to have no poverty and less extreme wealth. I think that it is disparity that causes crime and is probably responsible for mental health issues amongst those who feel they have missed out or see unfairness in the difference between their circumstances and those of people they see with a lot more than they have.
I'm not a communist - I think the theory is good, but it doesn't work in practice as human nature is more geared to competition and self-actualisation. If we were all paid the same and lived in identical houses or whatever, some would do the bare minimum, others would look for ways to get a step ahead, and most would be resentful one way or another.
I think that UK society suffers from the gulf in aspiration and ability to achieve potential between the classes, and that we would be much happier all round if we could find ways to even that out. For most of my career I worked in education, first in FE and then in universities. Many students in FE were there because their parents could claim benefits if they had children in education up to 19 years old. They were resitting O levels and later GCSEs, and often had no ambition, or even a basic understanding of what sorts of work was available to them. Some were from families where nobody had worked for years (this was the 80s) and those who did were in insecure manual employment. Qualifications were 'bits of paper' that gave people airs, and it took a lot of work to get past that and persuade them that they had as much right to learning as anyone. The thing was, though, that getting to university would almost certainly alienate some of them from families (and husbands), which is no small thing. Their loved ones sometimes held them back - because they loved them and didn't want to be left behind.
When I left and moved to universities in the 90s, the difference was marked. There were, of course, some students who were effectively the brothers and sisters of the FE ones, but far more were from families where it was a given that they would go into HE and the professions from birth. For every FE student with a chip on their shoulder was an HE one with a sense of superiority based on their parents' occupations or the fact that they knew they were likely to get a well paid job with some prospects of advancement. Generally the expectations self-fulfilled. On the whole they were all decent young people - it was just that their values tended to be different, based on a realistic assessment of their life chances, which were in turn based on their background.
If we could somehow get over that, and even out the things that get in the way of equality even when people's qualifications are the same (snobbery, access to social networks and contacts, the bank of mum and dad, the lack of geographical mobility caused by regional house price variations - even things like having children very young), and coupled it with a fairer and much more progressive tax system, the country would be somewhere I would be prouder to call mine.
