There are things that Amazon needs done to continue to run it's business effectively. Roads need repaired, crime needs to be kept down to acceptable rates, trash needs to be removed, they need to be defended from foreign nations, etc. The need of the corporations of our nation means that everyone, including these companies that don't build their own roads and militaries are on "the government teat".
The idea that money is better in private hands than in the collective hands of government is a story that is oft repeated, but is far from proven. Arguably, studies I've seen of late show loss of efficiency and increased cost when privatized. This is a requirement for profit anyways.
Further, money spent by government has had massive effect on economic growth. Hoover dam made the much of the West livable, nasa still had massive scientific output, and welfare programs are incredibly effective.
