Reminder For Americans Who Don't Think Unions Are Necessary

I had a conversation yesterday where someone told me that unions are no longer necessary because "high tech jobs" make them unnecessary and that our benevolent corporate bosses no longer abuse their employees.
Then this morning, I saw an ironic combination of headlines in Linkedin that spoke to that topic. In China, which has no real labor unions, tech billionaires have been forcing their employees to work 12 hour days 6 days a week, which they refer to as the "996 schedule". One of those oligarchs, Jack Ma, says that the concept of work-life balance is "pie in the sky". This quote was, of course, probably given while be lounged on a yacht somewhere.
Next to it was a headline about how young workers are increasingly miserable. Gee, I wonder why that is?
