This appears to be true of the Americans I know but this level of salary is.. uncommon amongst the Europeans (particularly the British) I know. I know you weren't speaking for other countries, but salaries are a lot 'flatter' over here.
Contractors will be earning at that level without too much difficulty but for a typical full-time employee to be earning $100K in London, say, they'd need to be an experienced manager or be into the 15+ year point of their career in my experience. It's night and day from the US experience.
This is part of the reason I work for myself. If I were in the US, I could earn $100K full-time pretty easily with my skillset. In the UK, it would be really hard work getting a similar position. Self employment wins for that here since I can just have American customers used to American prices anyway ;-)
