Well, like most propaganda pieces and works of disinformation it includes just enough truth to coat the lies. It also carefully shies away from comparisons between the US and North Korea itself and it's own problems.
There is no such thing as a Utopia, and what this seems to miss is that the US has a lot of flaws, people realize this, and this kind of "banal entertainment" exists as a form of escapism for people to get their minds off of those things.
The vast majority of people DO know about the homeless problem, and it greatly affects their point of view (one way or another) and comes out in terms of politics and who people try to elect for leadership, not to mention many community action programs and such. Granted as a big problem it's not one that is in the process of being solved overnight.
Statements about Americans not knowing where Britan is, being unable to tell you where the ocean is, and similar things, are of course entirely unqualified, and are worked in with the points about the banality of American culture (in of itself) to so as to hopefully avoid question. This sidestepping issues like Korea's tight control of information, where yout typical American... if he WAS really ignorant of some of these things, can probably find out just about any bit of general information he or she desires with their cell phone.
When it comes to politics/warfare/etc... you'll notice a lack of comparison with North Korea, not to mention a lack of mention of not only our motivations (on a lot of levels) for going to war, but also that it's a huge issue within the US where the population is divided almost 50-50. Our military actions being a huge political hotbutton in elections that continue to be resolved with single digit percentages. Right now Obama is leading the election which is less than a month away by a whopping margin of 2%. This means even if he wins 48% of the people disagreed with him. A point which kind of shows that the American people aren't being lead entirely mindlessly in one direction... unlike say North Korea.
When it comes to violence, that's an entire discussion in of itself, simply put I do not think violence is inherantly bad. However it's interesting to note that the US is hardly the only consumer of such games, and a lot of the most graphic games are created in the east and then not released to the west (despite protests from gamers) because it's feared they might offend the wrong people.
A lot of this didn't need to be pointed out, but I figured I'd do it anyway. The bottom line is the US isn't perfect, and we seek a lot of escapism, with our resources this escapism is very intense and of high quality, but people generally do not forget the reality they are seeking temporary escape from.
I suspect there might be a note of jealousy here. Probably because North Korean entertainment includes things like:

The music video (I hope that's a good link) that made a certain dictator's girlfriend famous...
In short it's equally banal, but of lower quality. Not to mention kind of disturbing in it's apparent message of happy domestic servitude.
