I don't need evidence to the contrary, what I said is the null hypothesis. If there's proof that every job lost to automation will necessarily mean one additional job opening in a different field, you are welcome to provide it. In absence of such evidence, I'm going to stick with the default belief: a job lost means a job lost, period.

And what is stopping that small business from starting up right now? Considering how terribly Amazon treats their workers, people should be lining up around the block to apply.

Dollars to donuts, the answer is the small business can't afford to start up because Amazon uses its monopolistic power to crush it, and that power will only grow as they continue to automate.
