I don't doubt that, and I also don't doubt that those working in the public sector would like more money - who wouldn't? But I do wonder whether we should question whether those in the public sector *should* have comparable pay? Maybe it should be higher than the private sector because it's a terrible career and awful working conditions? Or maybe it should be lower because of better conditions and benefits other than salary? I don't know.
It's not like people are press-ganged into working the in public sector is it. I mean they CHOOSE to go into the public sector and they can leave it and get a better paid job elsewhere if they think their skills are worth it. I think the two career paths are entirely different with a different set of benefits and values, and it's far more complicated than saying public sector pays X, private pays Y and therefore public must get Y. There's pension contributions, retirement age, holiday entitlement, the free electric bike (for example), gym membership, sick pay, life assurance, flexible working, god knows what else.
My point is there is much more to it than pay.
