"It's not just funding the baby boomer generation, is it? It is also a whole range of disabilies, physical and mental."
I think most people know this. Basically:
Health Care (NHS Care)
Paid for by: The government, through taxation.
Who provides it: The NHS (National Health Service)
Cost to the individual: Generally free at the point of use for UK residents (exceptions: Prescriptions (in England only — free in Scotland, Wales, and Northern Ireland.) Dental treatment. Eye tests and glasses.
Includes: GP visits, Hospital treatment, A&E care, Community nursing, most mental health services
Exceptions: Prescriptions (in England only — free in Scotland, Wales, and Northern Ireland), Dental treatment, Eye tests and glasses. These may require patient contributions or full payment unless you qualify for exemptions (e.g. low income, children, older adults, certain medical conditions).
Social Care (Adult Care and Support)
Paid for by: A combination of individual contributions and local authority funding.
Who provides it: Local councils, private care providers, or charities.
Means-tested: What you pay depends on your income and savings.
In England:
If you have savings or assets over £23,250, you usually pay the full cost yourself (“self-funder”). If your assets are below £14,250, the local authority covers most costs, and you contribute from income. Between £14,250 and £23,250, you pay part of the cost. The council assesses both your care needs and your financial situation.
In Scotland:
Personal and nursing care for older people is free, but accommodation costs in care homes are means-tested. Wales and Northern Ireland have their own systems, with different thresholds and caps.
Types of Care Covered by Social Care:
Home care (help with washing, dressing, meals, etc.)
Residential care (living in a care home)
Nursing care (care homes with nursing staff)
Support for carers or people with disabilities
This should make clear the division between what I meant as this "Care" that could/should(?) be covered by those over State Pension age paying NI. Any government would have to convince those of pension age that this insurance is worth it.
You are right to highlight “care” for people with special needs (also referred to as additional needs or learning disabilities) Once again this falls under both health care and social care, depending on the person’s needs and age. I don't think (or know) whether this would be enough. It seems the only analysis that has been done is on what putting NI on those still working after SPA. It is a large amount but nowhere near what would pay for this area of "care".
It seems governments and researchers have done very little to assess what could be raised by charging passive income of pensioners the same taxes as working income. As I think I suggested somewhere, that what we might shorthand as Special Needs" might be paid for by putting an NI tax equivalent on the passive income of those under SPA.
