I absolutely don't want to defend communism, I lived in Eastern Bloc and I prefer the flawed capitalism we have now.
But you are not really correct.

It's true that Bezos doesn't own the whole USA but 3 men has more wealth than 150 million people. https://www.forbes.com/sites/noahkirsch/2017/11/09/the-3-ric...
And the working conditions in Amazon warehouses are horrible. Workers in 50s or 70s had definitely better conditions and purchasing power. Despite all efficiency improvements, purchasing power of US workers is stagnating since 70s

The conditions improved because of Marx's teaching, without worker actions nothing would improve, it didn't happen out of capital owners' voluntary decision. It happened because of strikes and many were violently supressed. Just a few in USA: https://www.history.com/news/strikes-labor-movement
> Normal people see a rich guy and think "good for him, he worked hard, is smart and lucky"
Normal people are often hardworking (much more than capital owners) and sometimes smart as well. However to get rich, you must be lucky (usually you get born into wealth). Sometimes you need to be lucky just to get out of poverty.
I think majority doesn't care that their doctor is kinda rich and can go heli-skiing. They are angry that someone is so rich they can't even spend the money while his workers are struggling.

It's not normal or beneficial for society that 3 men has more wealth than 150 million of people.
