As restaurants start shutting down in advance of the $15 minimum wage.
For those who haven't worked in food service at all, lemme lay down a little knowledge for you. In a restaurant, a 3% profit margin is GOOD. If you start making a 5% profit margin, you might get audited because that's rather rare.
Now increase your personnel costs by 50%. Guess what happens? Your profit margins go into the negatives, and a negative profit margin means shutting down. It's no surprise that restaurant owners are choosing to shut down now, rather than when they're thousands of dollars in the red. They can see what's coming.
And while people look at the map and think the entire area around the Puget Sound is "Seattle", the truth is that there are plenty of other towns and cities all around Seattle that don't have to suffer under the kind of idiocy that Seattle does. And guess where those businesses are going to go?
Of course, they might not go anywhere at all. They might just leave permanently and decide that they no longer want to do business in an area run by greedy socialists who have no clue how an economy works. That's what I would do, after all. And I guarantee you that I'm not going to do a single bit of business within Seattle boundaries if I can help it, because the cost on me is going to skyrocket. Why should I waste my money in Seattle when I can go thirty miles and do business in a sane area for much less cost?
The one good thing to come out of this is that people all over the country can point at Seattle and say "Well, there's the end result of what you want to do, and I for one refuse to allow you to do that to my town."
