Hard disagree, the concrete evidence is that that can delete 20% of that bloated workforce and operate just fine.

If we don't run a business then we're running a business of a single employee. You are your own employee with 100% concentration risk. All of your income depends on one employee (you) with 1 source of income. If you had a business with 1 single revenue stream, then you would really focus on the health of that stream (Patreon). If you look around and realize most people are coasting and you can't really point any specific action you've taken that's boosted the numbers then you need to start preparing for that client (Patreon) to end its deal with you.

There's a lot of nice to have time and responsibility that an extra 20% of people get you.
