Best That You Can Do (Arthur's Theme) Lyrics

Lyric discussion by bsc_bigsixx 

Cover art for Best That You Can Do (Arthur's Theme) lyrics by Christopher Cross

Arthur he does as he pleases All of his life, he's masters choices Deep in his heart, he's just, he's just a boy

what does this lyric mean?

@bsc_bigsixx 22 years late but I believe the lyric is apparently 'masked his choice' which, when you observe his behaviour in the film (relationships / money) actually makes sense.
