Which increased in 2016.
It’s very definitely a bigger problem in the USA than the UK I’d argue. But this also very much depends upon what roll you’re fulfilling. For example in the UK the sight of, say, an Indian developer is not that surprising, albeit that the general opinion of them in the industry its unjustifiably low (any such problem is more often than not, a problem in procurement). However, a pure Indian tech businessman/founder in the UK or USA is rare. As it is with investment in BAME founders in the USA. As if anywhere other than the UK, it’s somehow automatically more primitive.
It gets even more surprising for “natives” when you start to compare the education systems of those other “primitive countries”, especially in the Arab or Persian world’s, only to find that the vast majority of them trounce the UK education system. The qualifications are just not recognised for political reasons and are also often, taught in a very different context and way.
For example, Saudi Arabia, that mongrel of primitive life and western consumerism, sets school years not by age, but by ability. It’s possible to Just pass the exams and go as far ahead as you want in a year (including several other years) as well as having teenagers who’ve never been to school sitting with 6 year olds.
In any event, not only should it come as no surprise to UK and US citizens, it actually should be expected. It is only when hitting University that such differences start to flatten out.
As illustration, comparing the PISA scores for standardisation.
