He still has time to do loan forgiveness "helicopter money" style. But even if all we got was an expansion of targeted relief programs I think it totally counts as fulfilling his talking point. The issue with student debt is that for some people there's no way out, but generally speaking college-educated people are more well-off and forgiving all debt would be a regressive stimulus that targets the wealthier side of the population. Targeted relief is a great way around that.
