Ah, but it IS bad for the world. Tens of thousands of unskilled workers will get replaced by fewer more productive workers, or by robots. Employers will not pay $20/hr to anyone not worth $20/hr. Any CEO who allowed that would soon be fired by their board of directors. They will simply recalibrate their workforces so that the only workers left are the ones worth what they are being paid.
The workers not worth $20 will be laid off and receive unemployment payments or otherwise be supported by the taxpayer. California taxpayers (already proven idiots by staying in California this long) will relocate to other less ‘progressive’ states in droves - to the detriment of every state involved.
If the “smartest” of the California morons move to smarter states, that lowers the average IQ of both California and the states that they flee to.
Any system that doesn’t allow markets to set prices is doomed to fail. Minimum wage is no different than any other government enforced price control - it sucks the life out of the economy by forcing suboptimal choices.
Well done!
