The trouble with these is that the don't create wealth. Education makes people employable. Healthcare restores people to health so they can work. However, neither of them adds to the total wealth available. On the contrary, they require wealth to be created elsewhere to pay teachers and doctors. As for clean energy, without subsidies, it can't exist. It, too, consumes wealth that must be created elsewhere to pay the subsidies.
Services may be an answer, but they must be worth enough to the wealth-creators that they are willing to pay for them.
Usually when it comes to business we use terms like 'market price' or 'net worth' because words like wealth and value too often get commandeered by cultists. So even though these are supposed to be econ threads we still get folks who say 'true wealth' is their own special meditations and others say its like, their dog maybe, so if you really want to say 'true wealth' is whatever comes out of certain factories that you've blessed then good for you.
