So, restaurants have small margins, that may be smaller if their employees negotiated better wages. Well, welcome to life. I grew up in the great state of New Jersey, where, since you are forbidden by law to pump your own gas, many people owned, ran, and worked at gas stations. And their profit margins were often in the one to two percent range, independent of the oil conglomerates. Somehow, often thru hard work, they managed to prosper. (Perhaps it was a generational thing; you took responsibility for your own success or lack thereof.) So, okay, if restaurants were to have to charge more so they could pay their employees more, then those restaurants that have bad food and poor workers will not get repeat customers, and go out of business. Such is the nature of the beast.
