Yes, companies with 30 employees are, in fact, money hungry because that's how the employees fucking eat. One person's recurring costs are nowhere near the recurring costs of dozens of people. WEIRD HOW MATH.
Stardew Valley, Undertale, Braid, all of these one-man (mostly) shows generated enough revenue to effectively retire their creators overnight but if they had to pay 30 motherfuckers with the proceeds... yeah, not so much.
