Modern life is so complex that people can't help with getting hit by stray bullets from all sorts of misfunctions of the societal and economic systems.

The stock markets tumble. Pensioners' funds lost. Whoops.
The Greeks cannot pay back their debts. Jobs creation in Canada slapped. Whoops.
On and on and on.

Complex systems, such as the societies which we live in as modern human beings, are prone to producing rounds after rounds of stray bullets. Stay out of trouble if we can. But how on earth can we?
