Blame can be placed on rich people deciding that they can "improve" education by teaching "grit" or something like this but there is lots of blame for teachers and administrators who don't make decisions based on research and evidence.
Research consistently shows that teaching students directly is the most effective approach but the idea that students can acquire everything on their own is almost impossible to get rid of because it sounds innovative and progressive.
Actually pretty solid practical education for the working world. I've had like 4 consecutive HR heads at my company try to teach everyone to have a growth mindset
And the hilarious thing about corporate "growth mindset" is they are absolutely going to punish you for failing, even though they ran you through a two hour seminar telling you how great it was to fail.
Have to let you know that mindsets are very much still an active part of K-12 education, especially with new hesitance around diversity. no need to talk about systemic issues when you have a growth mindset
Fun fact: there's a type of therapy specifically designed for people who feel that way. Dialectical Behavior Therapy.
Changing your thoughts/mindset helps a lot of people, but not everyone.
