This kinda reminds of my sister in law (in her 20s) who writes for a living, just earns enough to pay NI (so will get pension if there is one), lives at home (mum pays for everything and cooks for her- food to her liking), even has her own home office (siblings old room), goes on holiday to Europe (paid for by grandparents as she stays with them). Has multiple health problems but manages to access NHS fine because she doesn't need to work a 9-5 pm. Free prescriptions and when her earnings were low, she got universal credit -couple of hundred pounds a month.
Would probably inherit my mother in law's London house (do not begrudge her this as she needs it). Will never need to worry about rent or bills or mortgage or holding down a job. If you compare it to a lot of people including higher rate taxpayers, it's a pretty swell deal because even higher rate taxpayers have to be concerned about mortgage interest rates and possibly job security. I would say her quality of life is pretty high simply because it's stress free, she can afford all luxuries due to not paying bills, she is 100% secure as her mum's house is owned outright and her mum would never pick it out, she never needs to work a single day if she doesn't want to (mum would pay for everything and she will still be able to go on holidays and enjoy herself ). Don't know where you live but I am sure that you probably do have to pay for bills.
she laughed at me for using a private GP as I didn't have time to take leave to go for medical appointments. Why can't I just use the NHS, she does and it's perfect! She has a point, I am the silly one,I have a much more stressful life than her as I have a mortgage and need to hold down a job. The only thing I can say is that I am more independent (and my pride intact) but no one is giving me a medal for that lol.
But it's not sustainable for everyone to be like my sister in law. Sure it's a great life and very enviable, and I don't begrudge her for it, but I feel like I have to contribute financially to society. Even though she would probably have a more valuable property than me (as I own a London flat and her mum's house will appreciate more) at the end of it but oh well, I can say I pay a lot of tax! I go to a lot more restaurants and a lot more holidays than her though (but also have a lot more stress so I suppose it evens out).
Sometimes the right thing to do isn't always the easy thing. It is the people who push themselves career wise who pay the tax the country needs.
