Ah, so you already had democracy, that's good... but it seems the AI is quite advanced too, any worries about them getting a space race vic?
Also, I think one of the big advantages of the Eiffel Tower is also that it saves you the cost of researching mass-media. But of course, by now you already have mass-media so that point is moot.
Perhaps someone else (edit: Darkness for example..
) is more experienced with cultural vics? IIRC getting lots of religions is key, as well as stopping research somewhere around liberalism -> nationalism, foregoing the broadcast towers alltogether.
