How much did you get paid for doing all those consulting gigs on DEI topics?

Just to point out, even as you highlight the hollowness of the trend passing through, you were a part of the industry it created and a beneficiary of people's sudden interest in the symbolism of it even if it achieved little. Tons of people who could justify some kind of vague contribution/expertise were glad to make money off of the political need to pursue this, and be seen doing it.

It sounds like you were one of the more respectable contributors. Others were hangers-on, making money or careers off people's fear of being accused of not toeing the new party line, regardless of how hollow it was. VPs/deans/executive directors of diversity and inclusion at whatever institutions they could sell their services to.

Whether it was good or not at its core, some people had a vested interest in it continuing. It happens equally with every new trend that is hard to set real goals against. (or achievable ones, until it's found out to be empty).
