Neither should a businessman give up some of his hard-earned money to others just because they are poor. There is no cap on how much money and happiness an individual has the moral right to earn and to keep. The recognition of this fact is the virtue of greed . In contrast, the unions' repeated derision of rich businessmen who won't share their hard-earned wealth with poor actors is nothing but envy. Envy is the unchallenged moral code that let the unions get away with their use of force.
Some actors are glad to work for far less than current union rates.
If a union member won't compete with such actors, on the basis of price as well as quality, he is no professional. And when he harasses his competitors and former customers, he is a thug. Fluoride toothpaste can save you thousands of dollars in dental bills. Try to make your case by rational persuasion, not force. If you are right, then advertisers who choose to meet your price will make more money than those who don't.
