The problem is that our society is based on people working in exchange for the money they need to survive. There may be different or better ways to do things, but this is what we've got.
In return we get looked after by the welfare state, whether that's in the form of the NHS, pensions, education, defence, law and order, benefits etc etc, as well as having spending money to buy the things we want, as well as those we need.
As long as everyone plays ball and contributes there is (or should be) enough to go round, but when people - some of whose MH issues are caused by the stress of working - see others opt out and get given a similar lifestyle they will be resentful. This leads to extremism, riots and so on, particularly when there is less than is needed in the exchequer, so services are cut.
I think that this is where the Left can fall down. People with satisfying work often don't understand what it's like to get up at 4.00am to do a 12 hour shift in a factory on minimum wage, so it's easy for them to talk about work being good for us. It can come across as incredibly condescending, as does sneering at people who resent immigrants doing work that they used to do for more money. I don't blame immigrants, but my job was never at risk from people offering to do it more cheaply. I am not accusing anyone on here of not understanding - I am thinking of conversations I've had with friends around things like Brexit and pensions. I have to bite my tongue a lot.
The balance is difficult. Someone has to do jobs at all levels, and IMO it makes sense to pay people more for taking more responsibility/getting higher qualifications etc, and that is largely what happens. The problem is when people don't pay, (whether they are unemployable or not đ) but still get back. The result of that is that many of those who do pay in can't get treatment they need on the NHS, or have had to wait an extra 6 or 7 years to get a pension - because people are treated the same whether they have contributed financially or not.
We keep hearing about 'difficult decisions', and this is one of them. Can we let old people do without a basic standard of living, or let children go hungry because they (or their parents) haven't paid into the Welfare State? I wouldn't vote for that. But at the same time, doesn't there have to be some way to make it fair, and ensure that as many people as are able to pay their share? There should be higher taxation for those with more money, and that should be progressively applied. Nobody should earn too little to pay tax after working a full week, but neither should there be a tax incentive to work part-time, and childcare should not be a deterrent to work either.
Before anyone pounces, I am not suggesting (and have never suggested) that mothers go back to work when their babies are tiny - not at all. Parents should be supported through the early years with affordable (or free) childcare, and for a while it might make sense to subsidise part-time work. All I am saying is that this should not go on for decades, as the result is that there is too much of a burden on those who do work, and not enough in the kitty for the services many people spend a lifetime working for. What the government call 'working people' have carried the can for too long.
Having said all of that, automation has done away with many of the very routine jobs that used to employ those who struggle with responsibility, and AI will doubtless get rid of more, so the structure of society may change anyway.
