Lets say we drop the Salary/ Cost thing for a moment?

Are there any people who have worked in 2 or more of these regions? (US UK/ Eur Aus/ NZ)?..

And can you give an actual comparison in terms of WORK/LIFE Balance?

Does working in the UK/ Eur / Australia entail more time free at the end of your day?

NOTE: Should I post this in the EUROPE / AUSTRALIA centered forum to get better / more responses from people living there, who might give more insight/ comparative?
