There are other effects. Fast food is becoming moreSome agreement there, but still, I think some of the arguments against a liveable wage (usually that it will cost n-number of low-paying jobs and increase unemployment) are pretty easy to argue against. After all, take the case of your local McDonalds -- put those low-paying workers out on the street, and they'll no longer be able to afford the product: and they are among the principle consumers of that very product.
And really, though too many people like to tout the presumed "truth" that wages are the biggest expense -- that isn't really true for a lot of things, is it? I mean, most of the cost of a Big Mac is the product itself -- and the transportation that got it to market, and the cost of the restaurant, and heating the oil for the fries, and the parking lot...and on and on and on. So pay the worker who hands out 300 of these things an hour $5 bucks more an hour, that comes $0.06 per burger. That wouldn't be hard to build into the price of the thing.
automated, & this will be additional incentive to go
that route. The effects will vary greatly with location.
