I have read the new wealth of nations by Surjit Bhalla recently. He describes this phenomenon and also includes the reasons of educational and international mobility. Education has been as accessible as never before in the last decades. Further, emancipation (rated "good" by the author") has contributed to more women studying and entering the white color workforce. And globalisation has contributed towards people moving globally to where the jobs are. This has lead to an oversupply of highly qualified people and the stagnation of real wages worldwide. Exceptions are developing countries where demand is still higher and yet is leading towards increasing wages.
