Services have been privatised and regulatory conditions removed because Conservative governments are largely financed by business and, as the saying goes, "he who pays the piper calls the tune".
To some extent, Labour also shifted its position (1) in order to get the mainstream media onside and prevent it from characterising the Labour Party as a bunch of communist infiltrators (2) in order to remedy the dilapidation of our schools, hospitals and other public assets, it decided to enter into PFI contracts and other privatisation vehicles - a way of avoiding short term spending but with horrendous long term financial consequences.
We now see that the argument "we don't have the cash to invest up front"was a spurious one. The massive debt run up by the NHS because of the introduction of a system of marketisation, competition and privatisation has, at a stroke, been written off by this government - and billions have been made available in respect of all manner of business and social concerns. Had our country's NHS, care system, justice system, education system, transport system, etc, etc, been in a properly maintained state before this virus struck, it could be argued that would be in a far better position to tackle it than we appear to be at present.
As for the implication that those who work in education, social services, health and social care, environmental protection, etc, etc, are somehow peripheral to a thriving economy, I would dispute that. If we have an ill-educated, unhealthy workforce and poor infrastructure, such as efficient and reasonably priced public transport, that will affect motivation, efficiency and overall productivity.
I find it interesting that nurses, carers,librarians, environmental protection officers, child care officers, probation officers, etc, etc - because they are paid by the state/taxpayer - are seen as an unfortunate drain on the economy. Meanwhile, the many people doing non-essential (but often highly paid) jobs, such as image consultants, PR consultants, personal trainers, event planners, lobbyists, marketing and advertising executives, marketing psychologists, etc, etc, etc, are seen as acceptable just because they can command high salaries, and even though their absence would not be greatly missed.
