They are worse for the nation, for sure. They have more employees on public assistance than any other employer, due to low pay, and limited full-time position availability.
Amazon's bullshit goes waaay past retail though. and they did to independent online stores what Walmart did to brick and motor stores, but even more blatantly and directly. just look at what they did to diapers.com
the real scary part of Amazon is how much control they have through Amazon Web services. i get a chill every time i remember that Jeff bezos controls one of the largest backbones of the Internet. like imagine if Walmart owned the highways...
