Answer
Medicare and Medicaid helped provide affordable medical care to the elderly and the poor, though it still lagged behind that in most other advanced countries. Thanks to those programs and Social Security, the poverty rate among the elderly, which had been the highest among all the age groups, dropped drastically. Programs like the Job Corps and Model Cities provided job training to the young people who needed it most, and the Food Stamp program was expanded to help more working people with low incomes. Poverty didn't disappear. The fact that it didn't disappear was pointed to by some politicians as evidence of the futility of these types of programs.
