I work for a contracting company that builds software for utility companies ,(gas, electric, water,telecom, etc). While I think it's important that people get their heat, light, water and cellphone/internet, it's also complicated.

I'm looking for another job because I want to have more impact and I can't quit the system, buy an RV and travel around building poor people houses.
