Well written piece! Never stop learning. In a way there's an underlying political statement here on how diverse opinions and education changes perspective.
It’s not really “education” that changed his perspective but rather immersion in a group of people with a completely different mindset. The same could be accomplished spending time with them in a job, a volunteer group, a prison, etc. He also likely wouldn’t have changed his perspective much if he took the courses online asynchronously.
My hunch is that it’s pretty low.
