The problem here is that if this is systematic - and there is reason to believe it is systematic - then there is a chance that the next generation of elites (I'm thinking high level government bureaucrats, corporate executives and down the line towards more successful supervisors) might end up being measurably less competent than the last. Success at universities is treated as a signal of academic ability. If that signal is corrupt there are going to be some poor choices made. As troops are currently crossing the Russian border, it is worth reflecting that some decisions we do want the best and brightest working on.
