The parent company of all of the recruitment subsidiaries is a social impact company (https://www.causelabs.com/post/what-are-social-impact-companies-and-why-do-they-matter/). In all aspects its a normal "for profit" company (shareholders, staff, pension plans etc). The only difference is they are sustainable because they are highly ethical and although they make a profit (they must for all the reasons mentioned by other comments) their mission is to do good for society .
So, don't concentrate on the global recruitment agencies (they are the "not-for-profit" interface) and consider the "for-profit" fintech at the centre. It is profitable because it manages all of the portfolios that are gifted to new-hires. For example, placing 100,000 people in work means 100,000 * $5,000 = $500,000,000 Assets under management (AUM) for 24 months.
Although a lot of people on this forum understand crypto, they don't understand business. Thats why they make uninformed statements (which is understandable because this is new and making the statements is appreciated as we all can learn). The beauty of tokenomics is new business models are possible (just like Bitcoin disrupted finance, which not many people believed was possible). The tokenomics paper will show how society can help society profit from recruitment agencies which operate at cost...now that will twist your melon :-)
Fair enough, I am just speaking about the business model in which profit is returned to employees in a more direct manner. I am aware that the case may be different and still sustainable for a small company creating a sense of community around the idea of employees being the true beneficiaries of the profit and growth. Many large companies have something like this at a scale with incentives and stock options, so this is just making it 100%.
