While you are fair in your assessment as an employee, as a founder you kind of have to be a d*ck more often than not. It's an unsaid requirement of sorts.
Humility gets you nowhere, because if you have enough humility, you'll never believe you can compete with or win against giant incumbents in any space. You'll get absolutely crushed in negotiations and in the market if you are meek.
The challenge is to really know yourself and your work to be able to have enough confidence that keeps your ego at a healthy enough level that you don't actively repel people. You still have to work well with others, can't be d*ck all the time and to everyone. It's more challenging than one would think.
Entrepreneurship also evokes a survivalist mindset which is tough to manage, especially for founders who don't have financial security. Much like ego, it is a double edged sword. People think you might be ruthless when you're just trying to ensure your survival. An employee with a paycheck and job security has no idea what it means to not know how to be able to pay your bills because of cash crunches and random variables outside your control.
Micromanaging multiple things all day is what founders have to do to be able to learn, iterate, develop SOPs over time and keep refining them for efficiency. That means questioning everything and everyone.
Every founder is a bad founder at some point or another in their life, they are human too and it's just part of the process. Sometimes those mistakes can end up costing the business. This is why most people can't be founders or fail at it.
