Reminds me of this video on 'Chain Restaurants That Vanished Across America' I ran across earlier today. https://www.youtube.com/watch?v=ib2zljzT4P4

'Hitching your wagon to a star' has always been risky. Given Amazon's history? Whoa, would never want to be there.

This is not so correct and greatly over generalized. If this were true HVAC install companies would not be started because they depend on the manufacturers. Another example is the automotive supply chain Companies. If you meant don’t start a business that dependent on a single business that’s probably a better way to put it.

But finding a viable business niche that doesn't depend on some quasi-monopolist is getting harder every day.
