Imagine building a company from the ground up that is succesfull solely because it produces a lot of value to people, and yet random people on the internet still think all you care about is hoarding money and think they can make better decisions than you.
Here is the summary of the issue.
Firstly, pre-pandemic, unemployment was at an alltime low (and its trending that way to as places are reopening), very close to frictional unemployment rates, while Amazon was still able to roll out things like 2 day deliver and same day delivery. This means that it was able to staff accordingly. This in turn means that the pay that people recieve is worth whatever the working conditions are, and people can quit and go find easier job at any time. This is also true of people that are able to work overtime, for double the pay $30 an hour. Not to mention that benefits are also included, which as far as health insurance is a big plus for people.
Secondly, the number of reports of poor working conditions are far and few in between. For the scale of amazon, its expected that some warehouses are going to be run poorly. There isn't a single shred of credible evidence that this is a widespread problem. Also, with unskilled manual labor, there are people that are going to have a harder time than others. Taller pickers for example, have an advantage over shorter pickers that don't have to use the step stool. But again, 3% unemployment rate.
As far as unionization goes, this is the general gist of it. If the workers unionize, the service capability will undoutably go down. When workers realize they can take it easy and keep their jobs, productivity will go down. While its true that worker conditions will improve, the problem is along will come Walmart thats not as much in the spotlight, and offer better service and shipping while having shit working conditions, and people will just switch over because thats more beneficial to them. In no way shape or form the will continue supporting Amazon just because their workers unionized, out of the "good of their heart".
So Bezos is doing the correct thing by being anti union. Unionization is messing with the free market, which never leads to good outcomes historically.
If you care about the lower income people, then go out and vote for politicains that support higher taxation for the rich, social programs for the poor, so that ones living condition does not depend on ones job.
Also, for your brain health, get of the domapine fix that is the outrage of the internet lefism.
