Bookstores are closing all over the country, with or without a minimum wage hike. The problem is that no one buys books at mom-and-pop stores anymore. They buy them, generally speaking, at Amazon.

So while the last straw might have been a few bucks an hour, the root of the problem is that his industry is dying end to end (writers, publishers, retailers). A healthy industry can easily pay more than minimum wage to every worker and still be profitable -- look at Starbucks at its peak for an example.
