Pffffft, they should try having a baby in Singapore! My mate's wife dropped one here about six years ago and it cost the equivalent of £20,000.American women used to fly to the UK, stay in a hotel for three months then fly back after giving birth because it was cheaper than having their baby in the US
I would try and avoid getting sick here, too. The treatment here is first class but if you don't have private healthcare, you need to be filthy rich. I've had problems with my breathing and sinuses since I was about five years old. I had a procedure in March this year, which involved a turbinectomy/turbinoplasty/submucous resection; fronto-nasal ethmoidectomy; and, septoplasty/submucous resection. Should have been a one hour op but ended up being two and a half hours; next day the surgeon told me that "I found some surprises up there". For the op (including surgeon, anaesthetist, nurses, theatre, etc.) and a single night in a private room, my bill was S$35,000 (just over £19k). There was also the initial consultancy, CAT scan and three follow-up appointments with one more to come.
UK citizens don't realise how lucky they were with a health service like we used to have. Whether this would go some way to solving the issue or what, I don't know, but if you don't have a NI number then you pay up front or don't get treated.
