I cannot relate to this as I never followed Jack Black much. I am curious as to what people's opinons are - don't downvote this if you think it's my opinion, lol, because it isn't, but I thought it was spicy and I could see some interesting Fediverse feedback.
Are there many millennials out there that are both still working minimum wage food service jobs and are also old enough to remember Tenacious D and also have children?
Yes. People of all ages work minimum wage jobs.
