Wang Tzu-shou notes that boy groups are suited to the "roulette wheel" mentality of an industry that is struggling to survive. They are composed almost exclusively of unknowns, so, except for the training fees associated with the earliest stage of popularity, they require little capital input. If a company puts its chips on the right number, the money will come rolling in.
王祖壽也分析，偶像團體幾乎都由新人組成，除了走紅後的一些訓練費用，可以說是零成本，十分符合不景氣下找尋生機的「賭桌」心態，只要「押對寶」，鈔票自然滾滾而來。
