She'll be happy to hear that it has worked on numerous occasions throughout history!

Some were moe successful than others, but even in the ultraconservative UK they managed to create a national health service that hs proven difficult to kill off.

Sadly, I'll have to break to her that the fight never ends. The second you stop fighting for progress, some asshole will pop up and try to instill feudalism again.

Maybe the time has come to go back to the drawing board, and rethink some of the decisions that were made back then. Jefferson said every generation should have its own constitution. Maybe he was right.
