Capitalism is a race to the bottom. Maximum profit/gain and minimal loss.
Not to overly malign chicken sandwiches, but the point of capitalism is to charge the maximum that the market will bear while paying the least to extract it. And morals have nothing to do with capitalism. Even if it was mandated to have humane farming we would have a boutique pampered chicken sandwich (until they’re mechanically separated in 35 seconds) and foreign-sourced bleached chicken.
Anyway I prefer the tortured beef from Burger King.
