The majority already does not participate.

That doesn't change it, actually. Since the show still goes on. And enough people make their bet.

But if you were to imagine that NOBODY would vote anymore, then you would probably already have a totally desolate and disintegrated society, i.e. an absolute state of emergency or war. Or complete devastation after a war that has already taken place, with only a few survivors left. That would then not be a success at all, but the total defeat of a people. I consider this to be an otherwise absolutely impossible scenario, as never all the people of a country end up with zero or almost zero voter turnout, unless, see above.
