While collecting the recycling, the collectors steal (from my family multiple times), root through unlocked cars, knife open garbage bags, trespass, wake up sleeping people, and act aggressively towards anyone who interferes.
The collectors themselves live outside of the system of taxes and services, have no safety equipment to to protect them from broken glass etc, and end up in a constant cycle of unemployment, drug dependence, and other ills.
I feel like Berkeley manufactured this "picker" existence - it's an externality of trying to be the most progressive recycling town, and it's no good for anyone involved.
