Boomers have been saying this since the 60s and continue to say it even as they cash their latest round of checks.

Social Security is crazy popular. Even marginal trimming around the edges is politically suicidal. The only way to end the program is for Congress to shut down the agency and end the distributions. That's not going to happen so long as elections are even remotely contestable. Its the third rail of politics for a reason.

I would predict a military dictatorship before I'd predict an end to SS. One is practically a prerequisite for the other, and even then it would be dicey.
