It's simple, you create a charity and become the CEO. You then draw in funding streams from government contracts, private sector contracts and fundraising, to deliver your work.
You pay yourself a nice wage, the staff receive theirs, and year on year, recommissioning of contracts come in, or new tenders become available you apply for them. Same as revenue streams from the lottery fund and other foundations. As well as your fundraising, you'll also have major benefactors that contribute.
H and M with their global platform, reach and substantial money already available to be placed as equity could make a really nice sum for them as CEO of a charity.
This is why they network with the Nelson Mandela Foundation, The Kennedy Foundation. They become mutual benefactors to eachother circling big money at the top of the ladder.
