Thanks for posting @finnian. Actually the banks have a big advantage in the lending game that beats you on lendingclub. Fractional reserve. 90% of the money they loan you for your mortgage is a ledger entry that they create out of thin air. So even if the bank did the same as you and invested in Lendingclub they would make 70%. But they settle for your mortgage instead and make a crappy 39%. Makes you wonder how banks ever go broke.
