The quality of life in the UK for someone on £100k is very high. There’s no sympathy needed for people on £100k in the UK!
I'm sure it is. But how does having the option to retire in your 30s sound?
It’s sounds like an unrealistic pipe dream from someone in their 20s. Even on American salaries all it takes is one good accident (or even burnout) to derail the best laid FIRE plans.
Almost no one is retiring in their 30s regardless of circumstances.
