Exactly, machines require nor tax or payroll payments, no unemployment, work comp or insurance. And machines never ever demand a wage increase, at least not yet. People think that McD’s are gold mines, once they were, but increased wages, competition and loss leader menu items have sorely reduced the assay value of the ore.
You fellows talking about McDonalds might also remember the drink location. Once upon a time it was behind the counter and refills cost money. Many years ago I read an article that said the decision to move the drink counter outside and let people have free refills was caused by one of the minimum wage increases. When the cost of another employee exceeded the cost of coke syrup, free drinks won!
