As of 2019, Amazon employed 798,000 employees, so we're looking at almost 1 million people, earning $15/hour at a minimum, with 401(k), health, vision, and dental benefits. Absolutely nuts.

I'd be really surprised if these were real- '401(k), health, vision, and dental benefits'. Anyone can offer 401k without matching, medical without contributing to the premium.

Amazon publishes this page detailing the benefits + their per-paycheck costs [0]. The prices for the coverage received seem very reasonable.

Ah ok- I stand corrected - the medical is pretty reasonable. The 401k match takes 3 years to vest.
