Finance is a tool for greasing the wheels of an economy, and when it
serves its proper role, finance can be a very good thing. But it can
(and should) never be the economy itself; it is fundamentally
derivative on the labor of real people doing real work. By extension,
an economy that gives pride of place to what should be a tertiary
concern is an economy that is winding down and running out of ideas.
Just as the ascendancy of the lawyers is the death knell of an industry
(cf. the dying spams of the major record labels and the RIAA), so the
dominance of financial services signals an economy that has become
tired and spent.
