The higher the transaction fees, the more validators earn. There is no incentive to build tech which will lower transaction fees, even though it would enable practical use cases. Ethereum community is not interested in value creation because they know that value creation doesn't pay. They can earn more money just monopolizing media attention, attracting new investors and lobbying (aka corrupting) politicians.
Having worked in the industry, I've witnessed how they literally suppress innovations which would result in more scalability and lower fees. They only embrace solutions that are flawed by design to create an illusion that they're trying. Billions of dollars are literally wasted just to maintain the illusion.
I don't know where all that money is coming from. The crypto folks are clearly right about one thing; the monetary system is broken... But they seem to be making more money keeping it broken than fixing it.
