The definition of "Liberal":

person who cannot do math

How so, or what is your host ranting about this time?  Simple; our friend Mitch references the results of a Seattle initiative to raise the minimum wage to $15/hour.  Not surprisingly, a number of restauranteurs, facing a 60% increase in wages that already take up 36% of restaurant revenues, decided that they would close their doors rather than risk their already lean (4% on average) profit margins.

The kicker, in my view, is the liberal view that "businesses would simply pay the mandated wage out of profits, raising earnings for workers".   Sorry, folks, but a 60% hike in wages from 36% of revenue can't come out of a 4% profit margin.  And therefore a lot of low wage workers in Seattle are losing their jobs, which suggests another definition for "liberal".

person who talks a lot about helping the poor while doing things that hurt them, aided and abetted by an inability to do math or understand the basics of accounting
