If everyone worked for the greater good, the Libertarian platform of reduced government and personal freedoms (liberty) from oppressive government would be great. But greedy rich people will continue to poison us or pollute some way without government watching them. People will continue to be destitute in need of handouts or committing crimes without social security nets to catch them. We don't need the massive military spending we have, but we do need something more than the Libertarians would want.
Even though Libertarians are not generally anarchists, their anti-socialist government thoughts would probably lead to anarchy. I like some programs run as socialist programs- schools, libraries, roads, etc. Things that benefit the greater number of people being run by government with all contributing taxes toward them. Many Libertarians are Marxist socialists to a large degree. Again, I can agree in principle with them if I thought people were all working toward the greater good. But it never happened in China or the Soviet Union or Cuba or anywhere.
As far as civil liberties go, I tend to fully agree with Libertarians. Free thought is a philosophical viewpoint that holds opinions should be formed on the basis of science, logic, and reason, in contrast with authority, tradition, or other dogmas. They basically are for the rights of women, minorities, any sexual orientation, and any spiritual or non-spiritual practicing people.
I am way more in line with the Green Party that knows that any real change for the good involves a radical transformation of society for the benefits of all people on the planet, and wants to focus on social and environmental justice. They recognize that many people are more "empowered" than others and would work toward compelling such people to do what is best for the earth and all life upon it. They know there are no easy answers, but strive for non-violent solutions that democratically get everyone involved.
If the Green Party were empowered, it would not put all of it's focus on electoral politics as a way to bring change, but would be a bit harsh for awhile as it tried to bring about life-style changes so that more people (and the planet) would benefit more equally.
At least they seem to recognize that not all would work for the greater good and they would be better at dealing with that then the Libertarians.
