I am not sure it will hurt the really small business, startups and mom and pop work there already not taking a regular hourly paycheck. They live out of the profits of the company. but medium and larger size businesses that employ hundreds of people ? that is going to be painful. kiss all of the "dollar menu's" goodbye at the fast food stores. McDonalds, Wendy's, Burger King, etc, etc, etc. All of their upstream providers will be effected too. deliver truck drivers, warehouse workers, cleaning staff, common area maintenance fees for the property (landscaping staff).
Pizza delivery will probably disappear, can only deliver 3 pizzas stops in an hour, so you just added $7 to the cost of the order for the delivery guy.
