They most certainly are there to bolster skittles sales. Paying for coffee pods and skittles (all with a markup that turns a profit) where you used to have free coffee and donuts is not a perk.
"Most companies obviously produce products their employees can buy only since most companies target the middle/working class because most people are in the middle/working class."
I wasn't talking about most companies. I was talking about Ford and Walmart. Both companies use their own staff salaries as a benchmark for their target market and both successfully managed/manage to get their labor pool to turn around and spend their salaries on their products.
"If you are saying Ford raised its wages"
I didn't say that at all. I said it was no coincidence that his workers could afford his product. That doesn't mean he raised the salary of his workers to enable them to purchase, it means he used his workers as a representative sample of his target market and priced his vehicles so that they could afford them.
