He probably sacked people long before Patreon dipped; you don't realize how much paying employees eats into profits, until you have to pay them. Living in California, especially his part of California; $2,000 a month is on the low end and you have a couple different roommates in a small apartment; and that's just being a full time employee. So if they're not doing 40+ hours a week for him (and they shouldn't be, because YouTube), they have other jobs to carry them.
It's because I know how much paying employees costs that I'm confused. This is where I powerlevel a bit, but there's nothing I trust more than my own personal experience.
I have several accountant friends, one of which I'm incredibly close to because, A they do my taxes for free, and B they toss work my way every so often for some extra income.
From doing work with them, I know about one of the businesses they do the numbers for. It's at a mini mall, so not too terribly big, between 8-12 employees, plus one full-time security guard because our country is shit, and everyone is paid $3-$5 over minimum wage because no one wants to work for anything less.
Overall with the store composed of a mixture of full-time and part-time Managers, Cashiers, and Shelf Stockers, payroll is about $18,000 a month.
So with Jirard having, or had, 20 employees, plus the expenses of living in California, and the fact that editors are paid more than Cashiers, an estimate of $30,000 a month for payroll probably isn't too far off. So losing $2000 a month from the Patreon is maybe an employee and a half at most, but not enough to sink your entire company.
And this is the thing that pisses me off about YouTubers that become companies. Because they are either lying or they are bleeding money somewhere.
Jirard has stated that he had to deny giving people raises because he couldn't afford it and didn't want to want to fire anyone. And even Game Grumps has been saying they don't want to fire any of their friends since around 2017.
But ignoring the fact of the 20 employees for a fucking YouTube channel and cost associated with them, Jirard spent over 22K on buying every Wii U and 3DS game and was paying for a guy to make a Donkey Kong Country 2 Remix for every Completionist video. Arin and Dan each have a personal assistant, and it's heavily speculated that their community manager is paid over a 100K a year. The same goes for a bunch of other YouTubers, Roosterteeth, Watcher, the list goes on and on.
At some point these YouTubers shove their heads in their asses, hire a bunch of useless fuckers then get confused and panic the second they don't make as much money as they used to. That's when they turn to their community's generosity to help pay for their house payment/retirement fund. I'm glad at least some people give the right answer, which is no and also fuck off.
