slight digression - i'm not suggesting that people who work in nurseries need to be better qualified from the customers (ie my) pov, merely if the govt (and taxpayers) were to be persuaded to extend the education budget to pay the childcare workers better (ie value them more etc etc), there would need to be 'proof' of value for money. to be blunt (whatever your job entails in reality, noodle) childcare is viewed as something that anyone (as long as they have breasts) can do and requires no specialist training or knowledge. hence the minimum wage etc etc.
note - having used about 7 different nurseries in different parts of the uk, with three different children, one with a physical disability, i have been quite happy with the care provided. both from 1-1s and ordinary keyworkers, supervisors, and management. and i have a complete understanding of what the job entails. i think of the thirty or so childcare workers who have been in direct contact with any of my children, only one had a degree. your nursery is once again not an example of a general childcare setting if all of the staff have degrees, noodle. most nurseries can barely manage to get their staff through nvqs, and take them straight out of school because they are willing to work for next to nothing. just because they are cheap doesn't mean that they aren't brilliant childcarers, mind. it just means that their contribution isn't valued in monetary terms to society.
parents would not be able to cough up increased wages for childcare workers - it merely mean that more women had to stay at home and revert to the 1950s housewife role, it would have to be the govt. and i can't see that happening in the short term
