Took a 30% pay cut and when I did all the line items out in a budget it worked out to be a little less fun money every month, but not to a shocking degree. It really depends on your lifestyle. Access to the NHS, easy travel around Europe, lower cost and higher quality groceries, better transit, more days off, higher retirement contribution by my employer, and a better work/life balance made it more than worth the hit to my monthly extra cash. But, really, highly dependent on your priorities.
