What numbers are the top 1% pulling in?

I currently have a medium sized amazon fba business primarily doing wholesale.

I have 2 employees, and everything is fba. In 2021 I did ~800k, after product cost & payroll I was left with 120k. After taxes and so on I netted 78k.

Not bad by any means, but I’m at the point where I’m wondering if it’s worth it to keep pushing for growth. How big can I actually get – do I need to crack into private label to make serious money? How rare is it to make 7 figure profits solely with Amazon?
