I would argue for the inverse of that!
Where I live in Luxembourg, your salary advice has several categories of deduction - for a state pension (the highest state pension in the world, as it happens), for healthcare (one of the best healthcare systems anywhere in the world) for long term care in old age and so one. Finally when all those sums have been deducted you are taxed on what is left.
The specific deductions are paid into ring-fenced funds that then cover the outgoings for the healthcare system, for pensions etc.
It seems to me that that would be a far better system that that used in the UK today!
