I quite liked the fact that the "rich" family didn't give quite so much on a plate. I can see that only one child got a leg up but I was also unclear on what the other dc's aspirations were.
The "poor" family seemed to live pipe dreams and to have over protected their DC which cannot be good for their resilience. Bullied at school, move, unhappy at school - home school. If you don't have money for tutors/home schooling, you go to school, it's free. Also if there is so much debt, as a bus driver, why wasn't the dad throwing an extra shift? Why wasn't the mum doing a bit of catering on the side?
Musical dd annoyed me a bit. DD is musical, trained voice musical, (admittedly that took extra curricular lessons) so has more than a nice/good voice. She does a few paid wedding solos, and has a full-time, professional job - she's bloody good but for most people, even with talent and trained voices, earning a living from it is fantasy land.
They were both nice families but if you are skint, you can't be precious and what good comes from renting an expensive house because your children want to loll in their jimjams. Diddums. Those dc weren't being prepared for life's harsh realities despite having little money at home. The "rich" dd will graft because she's always seen graft. What will the poor house kids do when someone at work tells them to raise their game?
