Description: Presented at the Living to 100 Symposium, January 2011. The Community Living Assistance Services and Supports 'CLASS' Act’s designers and promoters envision the program as a noble plan to relieve the financial strain on Medicaid long-term care and enable disabled and elderly Americans to purchase more home care and suffer less nursing home institutionalization. This paper explains why CLASS, like private long-term care insurance, is doomed to failure unless and until the crowd-out effect of easy access to Medicaid LTC benefits is addressed.
