First, daycare workers usually have a higher risk of getting illness from the children. Nurses might have to lift their patients and risk of all kind of contagious illness at their work. Why they don't have a bonus for that risk, then?

And why a directive who is at not risk at all earn more than the wielder?

The risk happens to be a convenient excuse, but if we look at it logically, weren't all the nurses at risk with COVID? So why did they still make less than welders? or than male nurses for that matter. It just so happen that female dominated jobs aren't considered demanding or dangerous even in the middle of a pandemic that had their other employees working from home to not take risk. So explain, why do you think there weren't rises to nurses?
