As someone who appreciates a voice of dissent, I want to push back on some of this.
I grew up in a home with a very low socio-economic status, with family members who were gang affiliated, in and out of jail, dropped out, and drug addicted, to name a few examples. A huge motivation for me in school was to not be like them. I saw a lot of moments of failure rather than mastery. I had a lot of models of failure. I was constantly shown and given negative feedback. I definitely did not feel safe. However, these are the very things that motivated me to do better in school. So, I do want to push back and this and I do wonder about how else these skills are built up in students, because although I was the only person to go to college in my family, I was not the only person to go to college from my neighborhood.
