Anecdotal, but I have a pretty good before/after view on a community that got an Amazon fulfillment center. As far as I can tell, there hasn't been much impact on wages in either direction in that particular local labor market. Without strong unions, the labor market keeps warehouse wages at "just high enough that you can have a slightly better life than what you could get working in the service industry". There's always excess supply because warehouse work -- although physically demanding -- is relatively accessible.
