The above back of envelope maths ignores the overheads of interacting with the people who posted the bounties to get them to agree to pay up, and of the cost overruns on the class of bugs that look like two day fixes but take two weeks.

I've seen similar but less extreme examples play out in the private sector. 16 year senior architect making less than freshly hired software dev that was just an intern within the same company. Software developer pay is largely based on what you're demanding. In a lot of companies, there is a wide range of pay for folks doing literally the same job. They will hire a dev at $180k because that dev wouldn't go lower and turn around and push back to get another dev at $120k for the same level of unproven experience.
You have to keep finding clients (I'm sure it's easy now, will it always?) and pay all your expenses.
(And it's just a placeholder. $200k seems like it's at least in the direction of the right ballpark.)
the 60k buffer probably just covers the salaries of the multiple layers of management and facilities (building, cleaning...)
