Here's a radical concept: wages are too low. People aren't applying to your job because you're not offering enough money. Pay people more.
You claim to believe in a free market, then complain when nobody wants to work for you for starvation wages.
And given the avarice of corporations and the negligence of our federal government, it won't be getting better.
Granted, if enough of these shops then go under, the supply of jobs will decrease, and then the wages will drop (and many other market effects). Capitalism isn't even close to a perfect system for allocating these resources, but it does seem to be one of the best we have found thus far.
But to answer your question, yes I would. I voluntarily tip well above the amount you’re describing at every restaurant I eat at for this exact reason.
If a coffee shop can’t sustain livable wages, there are a ton of moving parts that could adapt. I imagine the problem is credit. It’s artificially hard to lower that shop’s rent because the landlord still has to deal with their mortgage price (and so on around the whole economy).
I do not believe that this situation truly exists, so this argument falls apart for me.
Also: many people are willing to pay more for “Made in USA”, even significantly more. Sewing and textile work is definitely more expensive here, and sometimes comparable quality can be found through overseas manufacturing (e.g. Arcteryx, Mystery Ranch). There’s room in the market for both, and the products are different enough for reasons other than some are MIUSA and others are not.
In other words, breakfast and coffee are not fungible commodities.
