I agree with this. Not sure how viable, but it'd be nice to see some kind of federal program which allowed for a 5-year transition program for people where their industries collapse precipitously (by some definition) and are guaranteed 100% their wages but must study/prepare for a new career.
Not sure how to avoid the occasional dilly-dallier who thought they'd make a good chef, but maybe we'd just have to put up with that fact.
