Wait, 'scuse me - 'infinite Mansion'? Of what speakest thou? I haven't been keeping up with the Avengers of late. There's kind of a class split, really - Moon Knight is a millionaire, Daredevil is a high-paid lawyer, Cage is a mercenary, Black Widow has held down a variety of jobs, but few of them high-paying, Shang-Chi has worked for the British government in the past, but he's basically a rootless wanderer, and Dagger is basically homeless - to the best of my knowledge, she's NEVER held down a job; she started her career as a teenage runaway, and her and Cloak depend pretty much entirely on the kindness of strangers. So only two of the Knights actually have anything in the way of financial resources; the rest are living paycheck to paycheck, if that.
