Doing well isn't only about what you earn though, is it?
I'm a single parent of 3, I have taught a shortage subject for the last 15 or so years (and did so at the beginning with 3 in primary school). I received a considerable sum in benefits to help me out. I should point out here that one of my children is classed as disabled, receives middle rate care and as such, I could claim Carer's Allowance or reduce my hours to be able to claim Carer's Allowance but I have worked (mainly) full time (just part time when my mum had dementia).
My role as a teacher is an important one to society as a whole, something most of us agree on, but yet still people are critical - critical that I receive benefits, that it's my fault my ex had an affair and walked out, that my children were the first into childcare and the last to leave, that I put my career before my children, that I should try harder to get off benefits, that it's not good enough they've had to subsidise me.......blah, blah, blah, blah, blah.
Civilised societies are not those that only respect and encourage high aspiration. Civilised societies recognise that everyone working is making a contribution - that we are all contributing to the greater good - and that is what needs respecting. Chase money - that's your choice - but respect that doesn't work for everyone and that when it comes down to it, many of us playing essential roles in our society aren't doing it for the money. That doesn't mean we shouldn't be afforded a roof over our heads, food on our plates or warmth in our radiators when we are out there working 60 hour weeks.
