When I call people not to work for Amazon, the most popular response is "if I don't work my children don't eat". That's true. That means whether for Amazon or not, we need to work anyway. Even if we open own business, we need to work (sometimes even more and with higher risk and responsibility).
Even if we have enough savings, we still need to work, we are still slaves. Slaves of our ideas. For example, I am on long term leave at Amazon and I don't write any code. But I work even more, because I am slave of my idea to change inhumane Amazon policies.
Finally, we are all slaves of the lifetime. Everybody will die and the death makes us slaves of the time. We are not free to make decisions beyond 50, 70, 90 years period. We are restricted by this time and we are not free.
Despite on all of that, we still have only one freedom. Freedom to choose, what we spend our life on. Will we work for Space X to save humanity? Or will we work for Amazon to destroy humanity? Most probably the medical nurse will be proud of salary paid to her for saving human life. But will Amazon HR be proud for bloody salary paid for supporting inhuman system?
