comparing the U.S. then and now

What interests me the most is that back in the day of WWII the people made numerous sacrifices whole heartedly. What's even cooler is that it wasn't just the main masses but people from all parts of the social scale; the movie stars and other elites took 'precious' time away from their careers and their success to give to many young boys who would never return home. it seems the nation as a whole understood that the true sacrifices that the newest generation of the time were making; that if the boys were lucky enough to make it home they would always have to feel the burden of their physical and emotional scars the witnessed in war.

This time however, the nation is fighting two wars and not really anyone knows or cares about it. Stars today are so self-absorbed that hardly any recognition goes towards the war effort or its soldiers; and if they did its a childish argument blaming the government or other groups.

Whats really curious, if no one is in for this war, why does it continue? many argue the government keeps it going, but other points in america's history where the mass disliked the way the country was heading and they protested and forcefully made the government pull out, (example: Vietnam) so does this mean the masses are satisfied with wars that seem to have no progression? We are in the technology age yet the people have never been so uninformed,

so my simple question is, what happened? When and why did the American people change?
