Haven't most peoples wages taken a real terms pay cut over the past 20 years? Unfortunately we have a bit of a mess of a country and giving everyone in the public sector a stoking payrise isn't feasible. People underestimate just how many people are working for the public sector. The extra tax burden and increase in costs to so many things would be a mess.
Its basically a 5th of the entire workforce that are public sector. You also can't do a straight comparison with private sector as the public sector usually has different perks. Teachers for example only work 3 months of the year
When it comes to the NHS, the biggest issue isn't necessarily pay, its understaffing, that would take years to fix though.
Yes. As I pointed out the only industry that hasn't undergone a real terms pay cut is finance.
