I'm in the U.S., but I stopped paying attention to national news years ago when I realized how much of a waste of time it is to worry about things I can't change when I have a hard enough time living consistently with my own values day in and day out.

It wasn't 40 years ago, though, and I don't remember having seen any actual efforts to destroy SS from either party. I've seen both sides refuse to try certain things to save it, but I don't remember anything I'd have called an attempt to destroy it.

I guess it depends on your definition of "destroy Social Security", but mine would include the efforts by Republicans to privatize it during the George W. Bush administration.
