The most effective way I've seen work ethic develop in a young person is by real world trial and error. You work hard in an entry level unskilled job, you are rewarded for that work, you develop something akin to self respect, pride, or whatever you want to call it, and that becomes the foundation for the rest of your professional life. Or you make a mistake and screw up, get fired, learn a valuable lesson, and reboot. Higher minimum wage eliminates these entry level jobs and encourages automation. In a world where the vast majority of entry level tasks have been automated away, what happens? Some kids will continue to leap frog from high school to college to medical school/law school to the operating room/the courthouse and populate the white collar professional ranks. But what about all the others? Automation and basic income aren't silver bullets for a better life.

Someone wrote: "wrong - those jobs are currently needed at a specific pay rate. They may not be needed if hourly wage is raised enough that automation is cheaper."

Well, that makes the argument more solid, not "wrong", as I covered that case already.

That data does no such thing - did you even read the axis labels?
