They had grown from ~100,000 employees in 2013 to 1.5 million in 2021. The growth rate would suggest they'd employ everyone in north america in only a few years.
While possible in theory, the government could never allow it. If a corporation were able to grow to that size, they essentially become the government. Bezos could simply tell his people to not send the taxes to the government and the government instantly collapses within months.
So unsurprisingly government went in and started restricting amazon. They can basically never grow again, they can't ever threaten the government's existence. Amazon to a large degree is now a US government ngo. Bezos is obviously no longer ceo and amazon laid off a group. And what has amazon done for the last 2 years, not much of anything.
