'To make the rich worker harder, we pay them more. To make the poor work harder, we pay them less.'
That really is the basis on which capitalism operates, and it's justified on so many levels - usually by pretending that we live in a meritocracy. A dentist lets people who have paid NI all their lives suffer agonising pain because they can't afford the treatment, and that's market forces. A train driver makes someone late for work and that's holding the country to ransom. A quick google suggests that an NHS dentist earns roughly twice the salary of a train driver, but that's ok because she has trained for years (although she doesn't pay anything like the cost of the course), while it's unreasonable of a train driver to want to hang onto his pension, conditions of service and job security, even though he works unsocial hours, has the lives of hundreds of passengers in his hands and risks having people jumping under the train he's driving. Train drivers should think themselves lucky to earn a bit above average salary, but dentists are suffering so much that it's understandable that they are refusing to take NHS patients.
I know it's not as simple as that, and I'm neither demonising dentists nor sanctifying train drivers - they were just the first occupational groups to come to mind - but that way of thinking is typical of why we have such inequality.
'Some posters'? Who are they? I am aware of the importance of financial services to the economy, but I am also aware of the importance of nurses, care workers and other groups who do not have their importance rewarded by financial incentives. If anyone can explain why that is, I might reconsider my opinion that it is grossly unfair. True, not everyone can be a good banker, but neither can everyone be a good carer - I know I couldn't.
