No hiring manager looking at resumes is going to put any stock into whether it says Google, Amazon or FB, or what school you went to. They will care what you worked on. If you bring with you this completely unjustified view that your coworkers are worse, it will show, no one will want to work with you, and you aren't going to get to work on anything interesting.

Your attitude is extremely concerning, you have a lot to be proud of career wise already, and you seem unable completely unaware of that. You have a solid base to build on and you could end up anywhere in a few years.

Amazon didn't hire you because they have a lower bar than anywhere else, they hired you because someone was impressed by you and wants to give you a shot. Extend them the same courtesy at least.

I think you need to seek psychological counselling ASAP, but until then stay away from Reddit, HN etc, as far as I can see your perspective is completely warped by the dishonest way that people present their own professional image, usually because of their own insecurity. Consider why people come to HN to brag -- it's likely because they aren't getting praise anywhere else.
