Nobel laureate economist Milton Friedman: "All of the progress that the US has made over the last couple of centuries has come from unemployment. It has come from figuring out how to produce more goods with fewer workers, thereby releasing labor to be more productive in other areas. It has never come about through permanent unemployment, but temporary unemployment, in the process of shifting people from one area to another."

Let’s Hope Machines Take Our Jobs: We Want Wealth, Not Jobs
https://mises.org/library/lets-hope-machines-take-our-jobs-we-want-wealth-not-jobsAs far as wealth inequality, what most people don't understand is that over time the average American has grown wealthier. True, the average millionaire has grown even more wealthy, but that is bound to happen if both of them increase their wealth by the same percentage. In other words, if, say, every single person in the country doubled their income overnight, the gap between rich and poor would also double. For example, if the richest person earns $1,000,000 and the poorest person earns $10,000, the gap is $990,000. If both incomes are doubled, the gap enlarges to $1,980,000, which is double the original gap. Both are now much better off, but the media would sensationalize this like they always do as a bad thing. "The gap between rich and poor has doubled overnight!!! Be shocked and afraid!!!"
