Oh some good questions!
None of them with an easy answer.
I'll give it a go as I'm on a 9 hour train journey and need a distraction for the irritating woman telling 3veryone on the train about her date (he's just not that into you love we all want to say.)
- "How would you change the class system"
It would take centuries as it's so ingrained however as a starter I would get rid of inherited titles. Scrap the house of lords, get rid of private education, massively increase inheritance tax, build a lot more social housing integrated with private housing, make higher education free, massively improve care for people in the care system, create a basic income, outlaw nepotism, make being classism social unacceptable (we are beginning to do this with homophobia). Make it easier for people to choose jobs they want to do rather than those they are expected to (my siblings who are doctors/architects and would have been much happier as a painter and a carpenter)
These are just a start and they won't stop my Mum sniffing at my husband using lounge instead of Sitting room, settee for sofa, toilet for loo or moan at my kids for speaking in our local accent but it make start making the class structures so imbedded. Fuck knows how we would fund it all.
