Just so you understand if the price of chocolate goes up by too much then people won't buy it. If people stop buying it, then the farmers don't get paid.
Same issue with McDonalds employees when they get $17 an hour, the dollar burger will be $5 and their regular stuff will be $10. No once will buy at that price.
Just look at Bernie sanders. He gave his employees a big raise and had to turn around and fire a bunch of them.
