I remember one of my seniors at work asking me how open source software manages to develop so much without a direct monetary incentive.
“There’s no lack of resources to give everyone everything they want.” <- is the point.

Our civilisation has enough people who like coding, willing to put their spare time into OSS, to be able to get good quality tools for use in all fields. Now all we need is for all of those people to be given enough spare time without having to worry about things like mortgages, loan payments and basic survival in some cases and everyone can profit (including the companies who would be giving them the spare time).
