Ok, here is an innovative, totally new, idea. Instead of giving them a minimum wage bump, maybe the corporations can give them company scrip on top of their wages. That way the workers can increase demand but especially in ways that are most profitable to the company. Of course, any current employee discounts will be eliminated so the poor don't get spoiled.
I think that after a while, this will be so successful that most (possibly all) of the wages can eventually be phased out for company scrip.
Imagine the joy and stability that McDonalds' workers will have if they have a wallet brimming with free McRib coupons!

We should also tell the poor that on their deathbeds... they will have total consciousness - which is nice.
