I generally like the concept of ISAs.<p>The current system in the US incentivizes colleges to provide an exclusive "luxury" <i>experience</i>, regardless of cost. Here the incentives are more properly aligned.<p>In addition, ISAs place a natural cap on college cost. Where cost could previously grow without bound (all loans are backstopped by the federal government), now cost is tied directly to the prevailing wage of the graduate. To the extent that wages signal the needs of the economy at large, I'd assume that ISAs would increase the number of graduates in in-demand fields at the cost of some fringe benefits.<p>The big losers in this equation are the lesser-paid but still socially valuable professions such as teaching. However, it's unclear to me that these skills could not also be delivered at significantly lower cost (as they were several decades ago).
