If we cut 1 million elderly from the Medicaid rolls, we reduce Medicaid spending by about 5%. If we cut 1 million adults, however, we reduce Medicaid spending by only 1%. We need to cut 5 times as many adults. If we want to cut Medicaid spending by 10% (which is far less than some propose), we’d need to drop more than 10 million adults from Medicaid. That’s almost three-quarters of all of them. If we want to cut overall Medicaid spending by 20%, then we’d need to drop all non-elderly adults, including all pregnant women, as well as about 10 million kids, or more than a third of them.
