"Watching and Waiting"

Yester-day I figured out the chords for "Watching and Waiting," and I noticed a musical feature that connects to the lyrics in this section:

'Cause here there's lots of room for doing
The things you've always been denied
So look and gather all you want to
There's no one here to stop you trying

The chord progression here is |: G major | D minor | G major | F major | C major | D major :|.  I'm pretty sure the song is in C major, so that D major chord contains a F# accidental.  That foreign tonality musically represents "the things you've always been denied."
