Well that's no fair; nor would they have had they have the same opportunities. Do your/our good opportunities entitle us to earn 50x what someone else does? Only in a colonialist "we got here first so now you work for us" sense.

Those who do have same qualifications are still payed much much less. Anecdotally, when Intel still had offices in Russia our salaries including stock awards were 3x or lower than those of the US personnel. Not because of difference in qualifications but because of the labor market (the salaries were very good considering other opportunities in my home city).

Thats bs. 10-50 times higher is for unskilled labor. You should try comparing a someone with an academic background in Lagos versus someone in Cairo .

Or the chance to educate themselves with for example photoshop to become a professional.

Because it is too expensive.
