It's easy to be sarcastic, but it's hard to measure social costs. "Stopped exploiting desperate workers" could mean paying people more, or it could mean firing desperate people and hiring people who are less desperate. If we're encouraging some mix of those two things, it's pretty important to figure out exactly what mix it is. And if there are alternative policies -- like say just giving people money -- that don't have the same complicated issues, it's pretty important to compare them.
