Those are the tough questions? What about: "What are the current plans to improve warehouse working conditions?", "Fast food workers have gone on strike and been on demonstrations in favor of a $15 an hour minimum wage; what is needed to get Amazon to unilaterally set a minimum $15/hour wage for all of its employees, associates, and other hourly positions?", and "If Amazon were to have and abuse monopoly powers, what would it look like?"
Personally, I'm glad he didn't ask those loaded questions.
