Yes apparently Lucas foretold a lot of things. On the commentary he mentioned the dedicated TV channels which are common now but didn't exist back then.

I just thought that in Italian I don't remember hearing the "buy now, buy more" line. Am I right? (I'm not at my computer now so I can't check it)

But I remember the voice saying "This is your resting day, be efficient in your resting" or something like that. I guess they didn't want to give Italians the anti-consumerism message of the film.
