They argue that decriminalization is better for the workers than legalization and that both criminalization and heavily-regulated legalization infringe on the workers' safety and human rights.
Legalization should be contrasted with decriminalization, which removes criminal charges from an action, but leaves intact associated laws and regulations.
I believe that we need to enact policies: emphasizing decriminalization while also creating spaces for the self-empowerment of poor and working class people.
