> Do you mean expensive in terms of taxes, the market commending a higher salary, or other reasons? The market. The US market for high-salaried knowledge work always pays more, whether is Tech, Finance, Legal etc. In general, if you're a high-earner/rich, America is a great place to be. If you're poor, the UK offers more support and protections, but this is a digression.
