I understand them, people are guarded and skeptical and they should be w/r/t the homeless. They are exploited almost by design at every level. This isn't what happened here, and I actually think what happened here is a model for starting to think about the "working class" going forward. The fact that lots of "working class" jobs are gone now is causing serious problems - but what if what we traditionally think of as the working class becomes low-level IT and other, newer fields. It's not about teaching everyone to code - it's about re-thinking the economy.
