It looks perverted and wasteful to us, but then one thing that empires are not about is the efficient use of resources and the spread of happiness; both are typically accomplished despite the economic short-circuiting - corruption and favoritism, mostly- endemic to the system.
Iain BanksPeople were always sorry. Sorry they had done what they had done, sorry they were doing what they were doing, sorry they were going to do what they were going to do; but they still did whatever it is. The sorrow never stopped them; it just made them feel better. And so the sorrow never stopped.
Iain Banks
