In theory, finance is supposed to act like lubrication in the machinery of the economy so that the economy serves families and provides for their material needs. People have to work, yes, but they get to keep most of the fruits of their labors. Sadly, as most of us now know, we, in the West, have allowed this ideal to be inverted such that finance (banks, financiers) takes too much of the wealth that is created in the economy. This causes the common workers to be in economic servitude in an economy that largely serves, and is controlled by, the kings of finance.
