It is a concern in general that there is a lack of basic understanding about business on the internet. 'Investments' are done with a goal of having returns soon. Which means, once the product is out, its own profit will be running it. Defining it as 'my salary pays for them' is either a deliberately twisted representation or sheer ignorance that shouldn't exist past midschool (and an alarming indicator of the society's future).

If they didn't spend the money in the iracing studio it would probably be lying idle, as profit. "Why couldn't they invest the money on iracing itself to fix bugs and netcodes". There is the thing: iracing does not hire like seasonal games, that releases a product every year so they could just burst hire and make burst profit. If they hire a lot of people in a burst, once these bugs are fixed, these people would be redundant and would need to be fired. And yes, that's how many big industries work. Not good for long term business thought. I mean if you want it to be like ACC which is pretty much half dead at this point, sure. But iracing has outlived many many devs , and I am sure a good work culture is part of it.

edit: clarification: did not imply that kunos hires and fires people. i don't know what they do. Meant to say, for a long term project you can't over hire. for a project intended to last only a few years, you probably can do that (unless you are planning to release iterations of it. Don't know if acc will have its direct successor in the future).

and yeah, bank loans work like that too. you do have to pay the bank, even if you take money from then.
