You're setting the bar at the federal minimum wage, which hasn't kept up with inflation for some time (not much good if it's raised if the cost of living rises faster). One can look at the federal minimum wage with disdain (I encourage folks here to try to live on ~$1200/month), and also observe that how Amazon treats its retail workers is still exploitative (both at fulfillment centers and the delivery network).

Regardless, a union is likely the solution for workers to improve their experience at Amazon at scale until there is enough political will (legislation/labor regulation) to stop treating these people as disposable.
