Not sure what tax rates are like in San Francisco however if you that kind of money in the UK you are going to be paying 40% income tax on a pretty large chunk of it. So after income tax you are left with maybe 50K. We also have council tax which in some places will make your eyes pop out. Not to mention VAT which is going to be 20% of pretty much everything you buy. On top of that house prices can be very high here for a family sized home even in a modest area so you're going to be paying a lot for your mortgage. Plus we have a huge amount of tax on stuff like fuel and anything to do with cars, not to mention that food prices are generally higher here than in the USA. OTOH medical insurance isn't really an issue as well as other things like more help available from govt to cover higher education.
