I don't understand what you are saying?
I work in business. If I need a specific skill-set that 9 competitors also need, the price for that skill-set goes up (astronomically) in a bidding war. By consolidating that skill-set into a seperate business, myself and my competitors can contract that business for our needs at a significant cost savings to all of us, without reducing quality. It's simply an economy of scale.
This is a very simple business understanding, and has been working in the US for over 200 years.
F1 does NOT exist to employ people. That employment exists because of the NEEDS of an F1 team, and if those needs are met elsewhere, the employment ends.
