We? There's no "we" in Hanson's piece, afaic, there's "they", but certainly no I.
There is a collective "we" though, as in, the American people. Generalizations can be drawn about the ebb and flow of the culture over time. I thoroughly believe that America's strength has become her possible downfall. Maslow's Hierarchy of Needs underpins and drives human behavior, and cultural trends are made of collective human behavior, (a multitude of individual exceptions notwithstanding).
Our strength has led to security and wealth, which have led us to be ever-increasingly occupied with dalliances, diverted from those values and behaviors which connected us to our greatness. "We" have allowed ourselves to be concerned with things that have no importance or connection to what made us great. When an entire culture is unconcerned with where the next meal is coming from, of from where the next horde will attack, it can occupy itself with XBox360, American Idol, MTV, and whether or not homosexuals deserve to be treated like heterosexuals. A culture that doesn't need to replace the dying due to illness and war can occupy itself with childless sex, and devaluing life. A culture that wants for nothing finds it easy to turn away from God.
You and I would turn the culture and country away from these grave errors if we could. But even so, I know I've participated somewhat in allowing the seduction of dalliance and distraction to overtake the nuts and bolts of life. I can't even say that it is wrong to do so. Obviously there's a point at which it becomes wrong. But we strive to make life better, more comfortable, safer, and more enjoyable. When we build that life, who can blame us for wanting to live in it? Yet we built it, and it took scant generations for us to forget what it took, what it cost, and how fleeting it is.
When I am fortunate enough to find myself in the presence of people from the WWII generation, or who were children during the Great Depression, I find myself in the presence of people who are touch with the great spirit of this country in more tangible ways than I am. Same thing when I am in the presence of people who were under the former Soviet Bloc. They know what it's like to live according to a hierarchy of needs that a very high percentage of Americans cannot relate to in any way.
That is the collective "we", and you and I are a part of it whether we like it or not.
