That is true. The American populace by and large is lazy. Unfortunately, it goes further than that. Many are close to being functionally illiterate and unable to read the political commentary which would inform them of what is taking place.
They have been dumbed down; from the time they went to kindergarten, no one challenged them to think independently or critically, and question the crap that was spoon-fed to them.
Americans may or may not be physically lazy (looking at the guts on people at the Chinese buffet and I tend to think they are). However, Americans are certainly intellectually lazy by letting the government and their propaganda organs think for them.
