You don't get it, I think? The point is to get the workers to quit or protest because they don't get paid enough, so that the place can increase the prices instead so they can pay their workers. If the place is still providing a nice service or good food or whatever it may be, you don't want it to go out of business. Just make a worker-positive change.
I'm trying to help the establishment, by changing their ways. Not by bankrupting them. And if they just keep changing waiters, surely the quality of service will go down and Darwin takes care of the rest.
I can not. Can you give an example of boycotting a business causing that business to raise prices to pay their employees a living wage? If so, I guess let's go with your thing.
