You don't have to lower the bar. There are other options. There is no fundamental law of physics that says a generation has to graduate at age X, so we -- the society -- should be perfectly able to delay that process for a year, instead of lowering the bar.
That said, there's something deeply wrong either with the society as a whole or with the HN audience if you read "poor kids roam the street like packs of feral dogs asking for money for food" and you say that the biggest long term problem is the lowering of the bar because kids skipped school.
