I don't understand your 2nd paragraph - the business wouldn't magically make more money if it was based in the US (we sell globally, including the US).

Healthcare here in the UK is totally free. I know only too well (to my detriment) that it's far from perfect, but I still believe it's a wonderful thing for all of society. Plus nobody needs to worry about whether they can afford to call an ambulance, and nobody is going to be bankrupted if they have a hospital stay.
