If these bozos were successful in getting a $15 minimum wage I wonder if they realize that this would drastically improve the business case for robotization of the fast food industry. The technology exists although admittedly still new. But robotization is where this is going without or without a minimum wage increase. Their efforts will just speed it up as well as their unemployment.
Any calls politicians make to protect “jobs” are done at the expense of market efficiency. That being said, I’m always surprised that more people aren’t using self-checkout lines at supermarkets, even when lines in the cashier lanes are longer. We live in a society where people are too stupid and unmotivated to learn how to scan a barcode into a machine, though, so I doubt that the market wants to rapidly implement these devices. This is why we must be ever diligent against the existence of the minimum wage.
There might not be robots yet capable of handling tasks but touch screens are certainly available and I do expect to see more of them show up everywhere. Could certainly get rid of anyone taking an order, accepting payment or delivering product.
Our local grocery stores never have more than one or two check out places manned by a real person but lots of self-check out areas. My bank has only one attended drive through area but two with do it yourself deposit machines. I would think somewhere along the line some of these people striking for more money would take a look at what has happened in other industries.
