Aren't professionals from different countries the same?
Since the treatment of professionals of all kinds is highly variable by country and partly determined by long lived cultural factors, there is no place to get a definitive answer unless someone has done some research on it. 

In some cultures, parts of India come to mind, professors are very highly regarded as they can provide a boos upwards in a stratified country. I've had students literally kneeling at my feet (just for lack of chairs) in my office. When I expressed discomfort at that, some students from India said that, no, it feel perfectly natural to be kneeling at the feet of their guru. 

In some other places, professors get spat upon. 

However, to say things are equal is a mistake. Often a good education depends on an institution having a lot of money for, say, laboratories, as you note. It is harder to get qualified to a certain standard in poorer places than in richer ones, just because of available resources. I suspect there is a positive correlation between the quality of education in a country and the economic well being there. It isn't perfect, of course. Even in the US, the quality of pre-college education is suffering from want of resources in spite of the US being a fairly rich country. 

But cultural differences can also lead to bad effects such as discrimination. Some well qualified medical doctors, moving to the US, find that they aren't allowed to practice medicine and the path to a license is very arduous.
