Do we reincarnate into similar or polar-opposite lives
No matter how you slice it, Buddha said we have been in every situation many times over.  In one sutta said when seeing a wealthy man indulging in all fine things in life and in another sutta crippled man lying in the gutter, we have all been there.  For this reason, it is enough to be tired of samsara.
It is reasonably to assume we have been in every situation and every world many times (except for world of sutavassa-world for non-returners.)
