Good question, and my personal approach is to invest in those
people--and a corporation is only as good as the people who
control it--who exhibit the most rational behavior, because it is
the rational minds of people that will overcome many of the evils
of the present system.
I invest in companies that produce quality products, that do not
do much business with the government or lobby for legislation,
that look to the next century instead of the next quarter, etc.
Since almost no company isn't without a few faults, one can
approximate this by investing in the market broadly /minus/ those
companies who commit the most heinous offenses: regulated
monopolies like utilities, military contractors, the government
itself of course (don't buy treasuries), industries that rely on
subsidies like recyclers, and industries with big lobbies.
