No worries at all, I appreciate the conversation!
I think I expressed myself unclearly, the tradeoff I'm unwilling to make is not because I miss services paid with taxes but because there are many dimensions to evaluate a country.
From my point of view, I already pay a private health insurance on top of my public one because the public one is just unreliable - and that's the main benefit my taxes afford me. Someone who can't afford it, will probably grade countries differently.
And there are so many factors to consider: culture, english speaking schools availability, weather, detached houses availability, real estate prices, if your spouse likes the country, anything that could be important for you.
I lived in Dubai and I'm not a fan of how they deal with personal freedom (eg. LGBT rights, alcohol / drug consumption, sex outside of marriage) even if I like how they deal with economic freedom. Also racism towards American / European expats from natives is pretty vicious (albeit not as bad as towards expats from poorer countries).
Some people are indeed happy to live in Dubai - personally I found that there are several countries which offer a better tradeoff for me, low taxes and a good quality of life (whatever your definition is).
