Marcus's assertions 2 and 3 seem particularly questionable - and of course, no evidence is given to back his claims. 

By Marcus's reasoning, governments would never set a minimum wage. This seems preposterous. Without a minimum wage, what protections do the poorest working people have? The current minimum wage is far too low and has not kept pace with inflation. Raising the minimum wage is a simple question of social justice and most academic research indicates that it will not result in significant job losses.

As for selling marijuana in government stores, Ontario and most other provinces have a long history of running profitable liquor stores with adequate controls. Why not pot?
