The Kickstarter bit is an incredibly stupid example that is honestly insulting to the intelligence of the reader. An indie or passion project is not paying anything near the salaries of a AAA studio and they're not leasing a California Metro high rise (if any at all). They have the overhead "footprint" of a very small business, which is nowhere near $10,000/head...unless you think your corner barber or bobble shop is doing $50,000 a month.
That number is before California costs anyway. You want to pay health insurance and whatnot to your employees. Software engineers are expensive. There's electricity and other expenses, office supplies, some baseline rent, etc. It can easily run up. You want to pay your devs a livable wage, and you also don't want to work them 100 hours a week. Man hours aren't free.
And it will only keep increasing, while game prices stay stagnant. Yet the demand for art and acting also keeps increasing, so keep that in mind when criticizing monetization models of games. The money for all that content and polish needs to come from somewhere. Games have been $60 for decades yet they're so much more expensive to make now.
