Planets' Meanings in Political Astrology, a Branch of Mundane Astrology
Here's my list so far:
Sun: supreme authority such as US President, Prime Minister, Chancellor, CEO, leadership. (Solar eclipses may denote the death or displacement of the head of state, national character and identity, major events, problems, or turning points for government in the eclipse year.)
Moon: the populace, we-the-people, the popular mood, national security needs, basic necessities, women's issues, health, agriculture, nurturing, our daily rounds, the general emotional weather.

Mars: males between ages 25--35 or so, military and police forces, violence, criminals, war, industrial concerns, arsonists; combined with Uranus, Mars may cause explosions, terrorism, attacks, gun violence; with Neptune, treachery, misguided motivations or actions, divisive elements in society, activists, protests, strikes.
Jupiter: clergy, churches, and religion, judges, law and legal systems, higher education, prosperity, publishing, banking, insurance; the upper classes; philanthropic institutions, especially if associated with Neptune; Jupiter and Neptune = speculators, wastrels, spendthrifts, inflation, grandiose planners.

As Pluto traverse Capricorn as does now (2011), the Earth's resources and wealth are steadily concentrated within a very few hands. Perhaps you've noticed...
