Now I'm realizing that for this whole idea to fit in line with my values I'd really like to use my investing to not only create a passive income for myself but also to contribute to making low socioeconomic urban neighborhoods better, particularly for kids who grow up in those areas, like helping them be less exposed to toxic substances and pollution, or have safer neighborhoods to play in, or more access to health/education resources. 

Find a real accountant anywhere on the planet who says otherwise and I'll eat my shoe.I'm not responding to you anymore.

Everyone on planet earth knows that there is an inherent difference.
