Well said. India would be a good example of hole diggers.
If software engineers were oil, India produces the most but unlike China you don't see them producing a Baidu, Alibaba, HTC, Lenovo, Tencent etc. Like you say they have given away their oil to the West by being laissez-faire in IT. It's why there are no Jack Ma, Pony Ma type recognizable names out of India. Instead you see a Nadella and Pichai emerge in the US.
But the same country has done the opposite with its pharma/generic drug sector by being pragmatically protectionist. It's no surprise that some of the richest people in India are now from the pharma sector, which is producing much more sustainable jobs than its IT sector is.
