text: I was just commenting on the idea that any increase in the cost of production will create an equivalent rise in prices, based on an actual recent increase in cost for me.
  
  So, I agree that every step in the supply chain is potentially vulnerable to cost increases, although even if production costs rise it may not get passed on. On the other hand, 5% of jobs are minimum wage, and many of those are restaurant/retail, so the number of minimum wage jobs that touch a supply chain can be high (agriculture) to low (specialized tool construction).
