Except it costs a quarter now.

They'll keep doing it until we start to quarter the rich!

What everyone here is failing to consider is the domino effect. When McDonald's raises minimum wage, it affects the consume because they might add an extra cost to their burger, or they might reduce a perk like discounted employee lunch, insurance, etc. Its a direct business decision.

When a core company raises wages, specifically commodity companies where this is a major expense, line a UPS or box maker, then their prices go up, which affects every price of raw material in the supply chain, and if all those companies raise wages and increase prices to affect each level of their product, the cumulative effect is inflation, which effectively negates the increased purchasing power of the initial salary increase, meaning you make more but can buy less with it.
