It's not that hard. Most of finance is about the efficient allocation of capital, and to this point in history our model has worked better than any other. It's not without its problems, namely the boom/bust cycle and propensity for fraud and periodic crises, but there are known solutions to those, if difficult to implement sometimes, especially when governments and regulators are captured to some degree or another. But to say that finance makes a contribution to society is not false.
