Rocketing refers to spending a great deal of money on a few important items while spending only an average amount or less on everything else.

“火箭式消費”指的是在幾件重要的東西上花費許多錢，而在其他東西上花費不多或很少。

Some people will spend lots of money on a few items they really care about, such as their iPhones or their SLR cameras, and then they will go downmarket to Wal-Mart to buy most of the other stuff they don’t care about. Rocketing is occurring at every income level.

有些人會在他們非常在乎的幾樣東西上花費重金，比如蘋果手機或單反相機，而其他無所謂的大部分東西則選擇去沃爾瑪這種低檔平價市場上購買。各個收入階層都存在火箭式消費模式。
