I also disagree that healthcare is uniformly cheap here. GP visits are not particularly cheap. You get to spend very little time with the GP and typically are sold a bunch of drugs you don't need (in Europe there's separation of clinics and pharmacies, which introduces some checks & balances).
To give another example, in Europe I used to go for a glaucoma test every year (due to family history) and pay about 20-30 euros. However, in Singapore, doctors look at you funny when you request to be tested for this as preventative health care is not really thing here. I did get tested twice for Glaucoma in Singapore (at the National Eye Center) and ended up with a bill of 250 SGD (~ 175 EUR) each time. The second time around, the doctor afterwards admitted that the bulk of the tests I had been given hadn't really been warranted. (Oh, and I couldn't exactly go in the same day by the way. There was a waiting list, though I don't recall how many days/weeks I had to book in advance.)
Finally, getting cancer has been known to bankrupt people in Singapore.
