Mexico's radix chart has a T-square between the Sun (5 Libra), opposed by Pluto (28 Pisces) and squared by Uranus conjunct Neptune conjunct the MC (29 Sagittarius, 0 Capricorn, and 6 Capricorn, respectively). The alignment of Saturn, Uranus and Pluto in a T-square sits directly on Mexico's radix T-square, indicating a very difficult time period indeed — and the ongoing square between Uranus and Pluto shows no sign of giving any relief!
In mundane astrology, the Sun represents the ruler of a nation, national character and major events. When in Libra we can see Mexico's leaders as nice guys, always trying to make peace, but especially trying to avoid conflict. Pluto represents dictators, the underworld of organized crime, death, financial and political power. With Pluto in Pisces we can see the collective obsession (as a nation) to avoid the criminal element by diving into the spiritual waters of their own unique blend of Catholicism and indigenous beliefs. We also see that religion (Pisces), i.e. the Catholic Church, is also the power (Pluto) there.
Neptune rules drugs, ineffectiveness, covert actions, fraud and scandal. In Capricorn, drugs become big business. Uranus represents revolutions, and progressive to radical movements. In Sagittarius, Uranus represents the high idealism of revolution, but also the lack of long term planning that plagues a country without sound infrastructure or social services.
With Neptune and Uranus conjunct the MC (the government), there appears the marked tendency for Mexico's government to be stricken with inefficacy and sudden swings in policy. Uranus is the ruler of Mexico's 11th house, which represents the legislature. Having the planet that rules the legislature (Uranus) conjunct Neptune, the legislature faces the same conundrum as the leader: lost in the Neptunian fog of idealism and failing to use resources or being able to rule effectively.
Mexico's Jupiter and Saturn are conjunct and nothing says big bureaucracy like that! Trined by the Neptune and Uranus conjunction there is probably a whole lot of talk of things changing, but the more things change, the more they stay the same. The Neptune and Uranus conjunction of their revolution must have led to more than a few people wondering after it was all said and done, what really changed? This conjunction causes whatever progressive ideas and policies which could have helped the poor and needy to evaporate in the heat of a siesta. Additionally, with a radix Jupiter and Saturn conjunction, the country is likely to have money problems, as the nature of Saturn is to put restrictions on money and growth, which is Jupiter.
