"As everyone learns in Econ 101, and immediately forgets, the purpose of the financial sector is to facilitate transactions and allocate capital… We don’t need finance to develop elaborate betting games and complex financial instruments. Financial instruments are only useful when they serve the purpose of better facilitating transactions or improving the allocation of capital." @DeanBaker13 https://cepr.net/crypto-and-finance-are-waste-and-a-drag-on-the-economy/
