Standard markup is about 100% on electronics from the bom cost, but things on a closed ecosystem that are supposed to make their money back in software and service licensing or normally so close to the cost. On something like a game console you are looking at a 10 to 15% mark up at retail. The wholesale price is very close to the bill of materials. The only company that really sticks out is Nintendo who sells at a 15 to 20% markup wholesale and then never lowers the price.
The really insulting thing about how Apple does it is the they add a 500 to 1000% mark up for storage ram upgrades. They even kept using 8 GB on the MacBooks when it was cheaper to run 12 or 16 GB ram ICS for the package size they were using.
Fry Cooks have to take classes on food safety. They are skilled labor. I’m not sure about the Amazon box guy but maybe both should have the trade union you need to be “skilled labor” in the actual sense of it.
