So, the founders aren't the ones that started the company then? When I say "founder" I mean the person that started the company from day 1: taking no salary in the beginning because the company wasn't making any money, taking a chance for months or even years that the company will go out of business or possibly succeed, or even working on the company during off-hours from a regular 9-5.
If a company has enough capital to pay employee #1, then yes, the founder is making a salary. But, at this point, the risk is considerably less and employee #1 shouldn't be getting anywhere near the same payout if the company gets bought out.
The founder also most likely has their own money tied up in the company.
Employee #1 can always get unemployment if the company goes bust. The founder will have their name and business credit history tied to the company if there are major problems. Employee #1 can just go find another job as if nothing ever happened.
"If the big-F Founder has a richer set of post-failure options than founding employees – and gets more beneficial notoriety even in failure"
More risk=more reward. If you are employee #1 and you aren't getting paid industry or above industry rates, then you shouldn't be working at that startup. If you want all of the glory when it succeeds, then you need to start your own company.
Have you ever actually started a company? It's not easy. Much more difficult (and risky) than being employee #1.
