finance doesn't magically confer certain properties on humans. human seek to satisfy their wants with limited means. does the pursuit of money lead to evils? sure, but money is only a stand in for other wants. money is a good because it is transparent in a way that other methods of accounting for the distribution of goods isn't. if you can quantify the resources that go towards X instead of Y and yet society claims to value Y above X you have some very useful data to investigate. contrast this with the primary competition for money as a means of distribution: opaque and non-fungible social favor. when a system of social favor redirects resources in a way inconsistent with values it isn't a simple matter of pointing to quantifiable numbers.
