Worth considering that purchasing power parity is nearly 35% higher in the US
Yes but you lose a lot of the that with the costs of health insurance and you have to drive absolutely everywhere and that's not free. I base that on my experience working in manufacturing/machine shops in the US (although that was a VERY long time ago) but I would concur with @laner that UK workers are probably better off.
this seems to suggest it's only 2 dollars more in the US (assuming avg 40 hour week), and taking into account the extra holiday pay in the UK and the NHS i think staff here might be getting the better deal
