Not all drug dealing is equal. A working class student who sells cannabis out of his dorm room in order to help pay for books is a lot less harmful to society at-large than is Phillip-Morris, which sells a highly addictive, dangerous product with the full legal sanction of the United States government. In light of that, demanding that the law be tough on drug dealing, without any caveats, is a recipe for mass incarceration.
It's funny that you should say that any such bill would have to 'not leave the poor in an environment of perpetual theft' in order to get your support. The fact of the matter is that the poor are poor because they are perpetual victims of perpetual theft. That their employers pay them far less than the value that their labor products is a testament to that.
The theft is not derived from capitalism. The theft is derived from politicians who seize property and employment opportunity because they want the political power and vanity associated with creating and administering anti-poverty programs. It's like a doctor who administers poison so he can sell the antidote. Don't worry, arsenic is definitely a cure, and you definitely need to take your dose! Vote Donkey.
I agree that drug dealing has varying degrees of severity. The proposition would need to differentiate between different types of drugs, without falling afoul of federal regulation.
