I also don't trust that people within the system can assess if what they're doing is good or not. I've talked with higher ups in fashion companies who genuinely believe their company is actually doing so much great work for the environment when they basically invented fast-fashion. I've felt it first hand personally how my mind slowly warped itself into believing that ad-tech isn't so bad for the world when I worked for an ad-tech company, and only after leaving did I realize how wrong I was.
