I remember Louis CK said he had a hell of a time trying to run his own comedy shows so he could offer lower ticket prices for his fans, but because every bit of the theaters were unionized it got really expensive fast and failed. They couldn't even touch the curtains, they had to pay a union guy to stand around all day and his only job was pulling a curtain cord at the right time. Which was some NYC rule.
And that's OK. At the end of the day, labor unions exist to help people and not robots.
People were worried robots were going to take their jobs. Then people were seeing their jobs get shipped overseas. Today, robots are finally taking over what jobs are left.
That union did just fine for America, it's better off for it having existed.
