My Dad died of stage 4 lung cancer last year, I've personally had a recent "scare" (luckily then given the all clear).
I don't begrudge anyone (regardless of income or status) how they respond or react to their own personal diagnosis, treatment and outcome.
Being jealous won't help. There is always someone with a better outcome/different outcome to you.
When friends posted about their or their relatives successful treatments on SM in the past year, it made me pleased that someone had survived this awful disease. My dad had exemplary NHS care up to and after his diagnosis. Most people do.
What a bizarre and unhelpful pint of view to have.
It really is like trying to instigate a race to the bottom.
