Yes, and for most retail businesses, labour is around 10% to 12% of revenue.  So with five full-time employees equivalent, that retail store should be doing around $6.2 million in sales.  To cover that $33,000 in increased wages, the prices of goods will have to increase by 0.5% (half of one %).  Is that really an imposition?  For a restaurant, where labour should be around 30%-32% of revenue, that increase in menu prices work out to 1.4%.  
Again, why are all these businesses in such a race to the price bottom and why should these businesses be subsidized by a minimum wage that is too low?
BTW, I own two businesses, have 12 full-time employees, and run a retail business like the retail business described by Ms. Wente.  I already pay my employees more than minimum, but my costs will go up to match.  You have to pay more than minimum for the right employees.  The real challenge is not cost, but rewarding your best employees.  Wente should get a calculator as should suedaninvestments.
