"No child left behind" may be an empty slogan, implying that something is being done when it isn't, but I can't see how it's really psychobabble.

Not all lies have the special qualities of psychobabble, that implication that, by pinning a quasi-scientific label on a difficult situation, the problem has been identified and effectively solved. "Sorted" as they say in London and around (a prime example of what you could call "soapbabble").
