Whilst someone who works at a desk in Pensions all their life can doubtless continue working into their 70s and earning a significant salary - the majority cannot, they have more physical jobs, drivers, nurses, construction, technicians, engineers, agri, logistics, warehousing etc etc.
This has vast wealth, huge numbers of multi millionaires and 100s of billionaires, vast inequality, yet, even now, some of the lowest taxes in Europe, why is it acceptable for people like Sunak to pay less proportionately than anyone on PAYE?
Why is unearned income taxed so very differently from earned income?
The issues are nothing to do with affordability, its about greed, those at the top wanting more "Trickle UP economics" if you like.
