I think it's commentary on the breaking up of the band more than anything. Sure, it applies to Paul, but it really applies to each of them. They were all prepared or desiring to move in different directions; they all really kind of wanted their own thing. A fitting, if depressing ending song. It's about selfishness and how it can build things (Desire for wealth and fame makes many bands) but destroys them just as well (Major fame makes them think each is the reason they rock, so they want their own gigs).
