One of the points in the essay was that statistically the tech industry is not the worst or even any worse than other industries in the harassment/sexism department. The difference (I'm interpreting/paraphrasing slightly here) is that the tech industry is high-paying and idealistic (for many) so it receives more intense scrutiny. E.g. there is a gender imbalance in nursing but you don't have The Atlantic posing smear-ish articles about the industry and groups of males storming the nets with social pitch forks.

I agree with you: our economic system is not the appropriate spot for social reform. Our economic system in America is capitalism. Maybe when I was younger–but I no longer have any expectation that a business will perform any altruistic act that does not align with its business model unless it's a PR stunt or the program is budgeted as employee quality of life (so it is effectively diced as employee comp).

I'm honestly curious what your idea of some low-hanging wins that make sense for a capitalist business to explore would be. Care to elaborate?
