「金は天下の回り物」というから、今は貧乏でもいつかお金が回ってくるかもしれない。
They say 'money is something that circulates in the world,' so even if I'm poor now, money might come around someday.
Compound of 回り (まわり, 'circulating') + 物 (もの, 'thing'). The exact historical derivation is uncertain, but it is conventionally associated with the idea of something that goes around or circulates.
