It's my fear that America has lost faith in itself. Individuals no longer believe in the American dream of personal achievement. People continue to treat the world as if it were a zero-sum game in which I can't have mine, if I allow you to have yours.
Freedom is an act of faith. It's a belief in individual achievement, starting with the belief in the potential for one's own achievement, but also a passing of that respect to others.
The US Constitution "lives" as a document only so long as the people of America have faith in its promise to secure the rights and freedoms of its citizens as individuals.
That means we must work to build a government that ensures equality of opportunity (education, school lunch programs, emergency services, military protection against foreign invasion, ...) recognizing that each of these opportunities is an investment from the community in the individual and the individual in the community. We need specifically to work against any government meant to ensure equality of outcome (unearned entitlement programs).
