I am not advocating lowering any bars. I'm just saying that those kids are as screwed now as they have ever been, and that this particular misfortune will not play in their favor in the future, as employers, government, and nongovernment institutions will be just as unsympathetic then as they are now.

A sufficient proportion of the US is willing to let those kids fall by the wayside, rather than do whatever can be done to boost them over this hurdle. It won't be adding another school year, and it won't be lowering the bar. It might be by providing housing, food, and petty spending allowance for over-18 kids still attempting to finish their high-school diploma.
