Yes, for example even after decades of saying there should be more women and minority people on corporate boards, it's all still dominated by white men.
California brought in a law banning all male boards in 2018 because the problem is so endemic. Not 1988, 2018.
A majority of companies in the S&P 500 have at least one woman on their boards, but only about a quarter have more than two, according to a study from PwC.[1]
So this is still happening now, and for decades most boards just had a token woman at best.
For me personally, when I found out about how unrepresentative corporate boardrooms were, that changed my mind about positive discrimination.
It showed me clear evidence that network effects were too strong, meritocracy is a farce and it had to be broken by forcing a cultural change, i.e. positive discrimination was the right solution.
If you go back far enough in my comment history here you'll probably find me arguing against it. But I learnt about the persistent gender and minority inequality on boards a decade or two ago and changed my mind.
You should too.
