Or, if you prefer, by meme.

People like sound bite/meme arguments. They sound good, they're easy to remember, and they don't bog the content consumer down with irritating details like subtlety and nuance.

Take your example. I create a meme, or assuming I happened to be someone who would be interviewed by a newscasters, make a statement saying, America is the richest country in the world but we rank 25th (or whatever it is) in level of health care. One can hear the reactions. Wow! Hey! That can't be right! etc. ad nauseum. Countering this statement requires a more detailed response. Questioning the methodology, perhaps. Which to the casual listener doesn't have anywhere near the impact of the original sound bite. Comes across as excuses, rationalizations. Plus, it forces them to think, which makes their head hurt.

Politicians figured that out long ago. The best comments are those that can fit on a campaign poster.

It's not unlike drafting a corporate email to people levels above you in the food chain. The rule of thumb is if you are writing to Directors, VP's and above, you lose them if they don't get the point in the first two sentences. Anything significantly longer than that they don't even bother to scan, much less read.
