Unlike most novels where love and wealth seem to come in disproportionate amount, the Merchant of Venice depicts relationships where love and wealth come together.
For example, Bassanio was quite a frugal individual but wasn't as wealthy as others like Antonio. Upon hearing that Portia was looking for a spouse, Bassanio borrows a fortune to present to Portia. When he got there to propose to Portia, he fell in love with her and got married. The marriage also came with a fortune that Portia was inherited and for Bassanio love and wealth came together in a package.
For Christian Lorenzo who eloped with Jessica, Shylock's daughter, love and wealth came correlating as well. Jessica managed to steal a fortune of her father's and most became the property of Lorenzo as well.
