Under-30 voters are “the only age group in which a majority said the government should do more to fix problems,” the nonpartisan Pew Research Center reported in November. In a Pew survey a year earlier, more than 8 in 10 said they believed that Social Security and Medicare had been good for the country, and they were especially supportive of seeing the programs overhauled so they would be intact when they retire. (Young people were also more open than their elders to privatizing the programs.)
