Yeah, when we talked about this (and I note again S24 ultimately decided against attending St Andrews), we discussed how an entry level job in the UK would likely pay a lot less than an equivalent job in the US. If it was just a temporary thing before a US grad degree or other move back to the US, that is maybe not so bad. But there is a reason a lot of professionals would like to work in the US if they can–the compensation can end up a lot better.
