Something I really hope to understand better is what opportunities we have to improve the efficiency of the labor economy, so that labor resources are allocated according to better information. This would drive down the margins of exploitative companies, while improving the efficiency of the economy as a whole. I'd like to think that such an approach is compatible with a "left-libertarian" marketplace-friendly outlook.
