I predict food assemblers will relatively soon be replaced by automated machines that can do a better, more consist job. Why pay labor costs for workers that call out sick, show up late, do shoddy work because they don't care when you can expense capital for machines that do none of those things?That's the thing, they'll never do that. People like to site that there's little historical evidence that minimum wage laws have negative consequences. But the minimum has always been so low as to be of little consequence in general.
Of course there are consequences. Lets talk about restaurant. Is it cheaper to have prep crew to wash and chop salad heads and other veggies into salad or to just buy premaid salad mix and throw it onto plate? What's the difference between two? Labor. If we compare Seattle with some cheaper inner city, I think that guy that chop salad in Seattle is about to lose his job in favor to some other guy that makes premixed salad for less money elsewhere.
