yeah, basically; also due to the lower cost of living in the UK compared to the US. the higher wages in the US offset the higher cost of living they face.
"Overall, the cost of living in the U.K. is 6.51% lower than in the United States. Rent overall is about 27% lower in the U.K. You would need $5,856 per month to finance a modest lifestyle in London, compared to $7,760 for the equivalent lifestyle in New York City."
