Americans or liberal Americans do not give a damn about the future, if they did they would not leave their grand children with a debt they created.
That's not fair.
Medicare, medicaid, and Social Security are helping conservative oldtimers, the military is a neoconservative project, and the right-wing has abandoned trying to handle educational policy, throwing it to the birds of feminist, multiculturalist, unionized labor in the name of emotivist, relativist, consumerism.
The left is backlashing against the right's insistence on ruggedly individualist pragmatic conformity to norms in families, churches, and businesses, and it's picking away at conservatism's base by victimizing its social outcasts. Conservatism's establishment abandons those who are outcast because it judges them as too impractical, dysfunctional, useless, or cost-prohibitive to be protected. It isn't willing to confront liberalism's destruction of social values, cohesion, or fabric, but rather anti-intellectually concedes to it while destroying its own intellectual base.
There is an ever-increasing amount of people who are originally victimized by the right, and later victimized by the left. You see this especially among half of the up and coming libertarian movement which doesn't sympathize with either conservative rugged individualism or liberal cultural relativism, but rather believes in objective morality.
I say half here though because the other half actually believes in synthesizing rugged individualism with cultural relativism in a dark compromise, and takes the same conservative excuse of "who's going to change things" as an excuse to not take the time, energy, and attention to discuss ideas. Libertarianism itself is not the answer, but there is an element within libertarianism which is.
