William "Salt" Hale, the Community Director of my non-profit startup Snowdrift.coop, heard me give a pithy and personal explanation of these things in a lightning talk at SeaGL last year, and he requested a video of it. So, with help from my student, friend, and fellow Snowdrift.coop volunteer Athan Spathas, I recorded that spiel and several others about the ways that cooperation and coordination matter in so many areas of life. Athan prompted me with a range of topics, and I explained how they all connect to these social issues.

I don't have answers to everything, I just know some things about the nature of the problems. But that's a good place to start. Too many people today believe a strange individualism that denies the fundamentally social nature of these issues. So, I hope these perspectives provide some value and insights or at least a moment of entertainment.
I may record more such videos given enough requests, and I'll do what I can to answer questions or provide more references and related links if I can find time.
