I don't see link between your comment and the main topic. Plus this is typical french bashing: we french people financially contributed to your PHD, and you're basically saying that we are racist like some policemen who are just fed up with the problematic mass low-skilled immigration consequences.
Maybe you should go see an optometrician. France did indeed contribute to my Ph.D: mistreatement and exploitation. FYI, like most of the "immigrants", I have done research for free (yes, free with no scholarship), paid more taxes than you are probably doing now and contributed to your retirement (not mentioning the contributed research). So please, don't spill what you've just heard from your far right politicians who have nothing to do than bashing anything that relates to africans: Like bashing the French education minister because her parents are north-african immigrants.
