I am very sorry to tell you but no, people will not stop contributing once they know.
- People don't really care about anything not effecting them directly and immidiatly. Thats just the truth look around.
- Don't tell your neighbors to change, they will react hostile and you will probably drive them away further. ALWAYS talk about how these companies are mistreating THEM.
Personal responsibility is a brainwashing tactic from big corp to blame yourself and your neighbour for systematic Problems they created. Don't fall for it.
