Please give a few examples of countries with a healthy middle class; in Europe, where I know the situation best, there are no such countries anymore. The Emirates have some, but they have zero income tax, so it is politically not correct to use it as an example.

You have not defined middle class, so there is danger of operating with different standard. But people in Scandinavia do pretty well, overall.
