That's an inevitable consequence of the design of BGP. Each node knows only about nodes to which it is directly connected. Given the size of the Internet, it is the only feasible solution. IP does have options to control routing, which could in theory be used to ensure symmetric routing (or nearly so), but they are so easily abused that everybody simply ignores them.
