This is a good empathetic arguement for socialism. Unfortunately many terrible people like the second solution of just killing off the unemployable in various ways. This was usually done through invading neighbors which increases ones own power and reduces your own unemployable workforce. If you don’t want to kill off your own people, you may also have a minority group in your borders that can be put on trains for removal in various ways. Unfortunately the Karl Marx saw a common issue in history and proposed an empathetic way to solve it, but most people I know are assholes and prefer the second option.
