10-4. Apparently, that was including the capital cost of design and development. With today’s manufacturing processes, that cost comes down for each additional machine, especially when produced on a production scale. I would submit the cost, including maintenance and updates would be much lower than even the $7.50 number because of the elimination of employment costs, overtime, sick days, short shifts and especially in efficiency tied to retraining constantly to keep up with the constant turnover. One machine alone could effectively replace up to four people per shift and we know some of these places are open 24/7.
I am in the design and development business and have been predicting this shift since the first coordinated calls for substantial raising of the “living wage” bullcrap started to surface. As most of my family is in the food service business, I have seen this first person since the early 70’s and the reasons I only worked it part time to help them out while I was focusing on my engineering education to be as far away from it as possible.
