You see this in the media fairly often, and it is occasionally brought up by (losing) courageous politicians like Bernie Sanders and Elizabeth Warren. Large majorities of voters support benefits programs, particularly Medicare and Social Security. These politicians can’t get elected though because of the anti-tax narrative that is convenient for the wealthy and powerful interests that buy and own our successful politicians. So around and around we go.
Sensible policies are obvious. Incrementally lower eligibility ages, or at least allow younger citizens to opt in at cost. The latter would be win-win for everyone except the finance and insurance industries.
Political strategies are less obvious, and nothing that has been tried has worked lately. Politicians need to reach the same working class and professional crowd that is susceptible to the anti-tax message. A somewhat disingenuous approach would be to exaggerate the reach of those who are actually trying to dismantle the popular programs. Use their words against them, even out of context,and make their political and private associates guilty by association. Give the race and gender rhetoric a rest, because it is dividing the majority of voters you need to support sensible policies that are going to benefit disadvantaged groups the most. It’s a dirty game, but it’s a game the other side is going to play like it or not. Expand the benefits first, let people see and understand what they are getting for their taxes, and the benefits will be hard for future politicians to take away.
