I'm surprised no one here has yet name-checked Tom Wolfe's
Bonfire of the Vanities. There is a famous comedic passage in which Sherman McCoy discusses his expenditures relative to his (vast) income.
EDIT:
One breath of scandal—
—his spirits plunged even lower. One breath of scandal, and not only would the Giscard scheme collapse but his very career would be finished! And what would he do then? I'm already going broke on a million dollars a year! The appalling figures came popping up into his brain. Last year his income had been $980,000. But he had to pay $21,000 a month for the $1.8 million loan he had taken out to buy the apartment. What was $21,000 a month to someone making a million a year? That was the way he had thought of it at the same—and in fact, it was merely a crushing, grinding burden—that was all! It came to $252,000 a year, none of it deductible, because it was a personal loan, not a mortgage. (The cooperative boards in Good Park Avenue Buildings like his didn't allow you to take out a mortgage on your apartment.) So, considering the taxes, it required $420,000 in income to pay the $252,000. Of the $560,000 remaining of his income last year, $44,400 was required for the apartment's monthly maintenance fees; $116,000 for the house on Old Drover's Mooring Lane in Southampton ($84,000 for mortgage payment and interest, $18,000 for heat, utilities, insurance, and repairs, $6,000 for lawn and hedge cutting, $8,000 for taxes). Entertaining at home and in restaurants had come to $18,000.

It goes on. The guy needs Mr. Money Mustache.
