EADG, can't force you to like Singapore food, of course. It's all a question of personal taste. Like I've been to Greece 4 times staying a week to a month each time and I still do not like the food there.
You were a little harsh on the Western food on the island though. I've been to many Michelin-starred restaurants in Europe and I do not think too badly of Iggy's (Regent Hotel), for example. There's another one operated by a Belgium chef and he makes the most amazing foie gras dishes. And I love chilli. And only those who love chilli would understand how life can be lacking something without it. Threshhold of course as usual is personal.
Check out Chubby Hubby's blog, if you wish, he has interesting reviews on restaurants in Singapore and elsewhere.
I'm sorry for your bad experiences with local estate agents, though some may be doing ok since I've just read a Dutch expat praising his in his blog. Myself, I'm just a HDB kind of poor chap. But the public pool is nearby and only costs 1 buck per entry.
I wish I have our taxi system wherever I live. Try getting them in Paris, Madrid, Stuttgart or Modena - you'll end up having a few cars like I did. Or take the bus (if there is any).
Sorry for your lower pay too. That's personal, of course. Though from what I could see, many of my friends who are married to Europeans all managed to get the spouses to return home with them after living in Europe for a few years - because at the end of the day money stretches more on the island. Unfortunately that would depend on the industry and sector. We have no opportunity to return to Singapore, for example, since my spouse works in the automotive sector. Started to get a bit excited hearing about the F1 coming in in Sep, but that's just an annual thing, wouldn't be able to keep us a whole year in the country.
Rude people, I agree with you, though maybe you should try HK. But probably you'd be spared that if you do not speak Cantonese or shop very local.
Fashion too, I suppose is personal. Like the Singapore girls I know living in Germany and Italy begging for copies of Her World from anybody returning from the island. Italian fashion is too bling, German too sobre. They still prefer Singaporean. Me I'm torn between Spain, Paris and Singapore. My French spouse thinks Japanese women dress horribly in general.
Here in Europe I do not go to the cinema (except in the Champs Elysees in Paris). The most dingy halls and stupid reservation systems, though people maybe do behave better - if you ignore the littering.
Japan, US etc too far? Try living in Europe, dear. I've travelled much more living in Singapore than I do ever since moving to Europe. Just getting to an airport is often a nightmare in most European cities. But if Australia, Indonesia, Indochina etc's your destination, Singapore's great.
Health insurance, you should hear me whine about this over here. You pay every month for it whether you need it or not and when you do, the service is usually crap and you end up having to pay some more. Most Italians for example pay for private insurance on top of the compulsory public one. And I know things are not better in the US, for example, since all the Americans I know whine about theirs back home saying how much better things are in Europe (!!!).
In Singapore we have NO insurance coverage (aka no need to pay every month whether you like it or not). But medical care is good and reasonably priced, I return home for all important interventions and they would still cost me less without any insurance - compared to what I would need to pay in Europe - after insurance. The only problem, and it's an important one, is that if you have a long-term illness in Singapore, you would usually be grilled. A whole family can get indebted for that. But the idea is to place the responsibility on the individual and not burden the rest of the population which if you look at the enormous deficits in Europe you'll understand why. Still, I agree that we should really study the system seriously. I've currently 2 relatives being left to die of cancer because they are poor.
Anyway at the end of the day whether we like a place or not it's all really personal. In my experience it often also happened this way : I didn't really like Stuttgart but when I started living in Modena, suddenly Stuttgart seemed like paradise and so on

And I love Singapore and regret leaving it, but then I know I also hate the lack of space on the island and the fact that I knew when my neighbour moved his furniture in his living room and he knew at what time I showered last night.
Je pense donc je suis. Le reste du temps, je ne suis qu'une fleur.
