While Amazon clearly does not have their workers best interest in mind, this is not a short-term profit driven company. On the contrary, Amazon is focused on growing and solidifying its long-term position at the expense of short-term profits.
The company doesn't do anything by itself. It's all driven by people, and people who work in a company changes. Effectively any company participating in the for-profit culture of capitalism favors short-term shareholder benefits over long-term societal ones, because that's simply how the system works and prefers.
