Despite how Bella rejects Rokesmith for being poor, a part of her realizes that it’s not good to be too greedy. Mr. Wilfer demonstrates his close bond with Bella in this passage, supporting her even as she makes decisions that he himself didn’t (like prioritizing money in marriage). Mr. Wilfer’s marriage isn’t perfect, but his decision to marry for love instead of money seems to have served him much better than more “mercenary” characters like the Lammles, who marry for wealth.
