something either that making you a lot of money,or that allowing you to spend a lot money并不是独立主格结构,请注意something是个代词,指代good situation,对进行详细说明,而THAT的作用则是引导了一个定语从句,但是注意THAT引导的定语人名省略了成分,完整的句子结构是something either that will be making you a lot of money,or that will be allowing you to spend a lot of money.
