It's nice to believe that an Amazon could basically found a new city/locate in a small one or run-down one. But I tend to agree. The premiums they'd have to pay to attract people to work in effectively a company town would be significant. It would take years to build out infrastructure and amenities. And it would probably still end up as a rather unattractive monoculture under many circumstances.

You can probably bribe enough people enough to work just about anywhere but it's going to be an uphill battle.
