As others have said. It depends entirely on your lifestyle and expenditure. A few years ago if I saw people earning £50k I'd have thought they mustn’t have a worry in the world but now I'm not so sure.
I now earn a salary that I once could only dream of yet I still have to count every penny, bigger house, newer cars and so on. Most people tend to live a life that they can just about afford. If you'd have told me 10 years ago I'd be earning what I do now I'd have imagined a life of luxury, sadly that isn't the case! Always chasing the end of the rainbow!
