Pure bullshit. You can't pass it on if you don't have a viable business without labor subsidies, otherwise you can. And remember: 1) it's phased in over time! ; 2) If the minimum goes up by 108% (7.25 to 15) over 4 years, the amount of labor cost increase passed on per annum to maintain constant profits, in the majority of cases, will amount to a tiny fraction of 108% of final price, the only exceptions being cases where under 15/hr labor is a major part of a final products cost. And even there its not much per year when spread out over 4 years.
If you can't afford to pay your full-time employees a living wage you don't deserve to be in business. Find something else to do, like go to work for someone who knows how to run a profitable business.
