In the US, bullying isn't a problem so much as it is a national past time. Americans love power, and people with power; one way to increase your own (apparent) power is to decrease the (apparent) power of your rival. And then people will vote for whoever they think has the most apparent power (so long as that person has the right capital letter next to their name on the ballot.)
We do a lot of things weird here. Blow a guy's head off during prime time television? What, you're telling me you only did it once? Do it five times, think of the advertising revenue! Oh, you want to include a scene that shows a woman's nipple for half a second during that same time frame? No, sorry, you have to go to jail now.
I think that America (and Americans) has an incredibly amount of potential, but it's significantly hampered by our weird mix of "morals" and in-fighting over issues which, relative to the country as a whole, are fairly irrelevant but get all the focus.
