By the time Ku quit the marketing cooperative, Taiwan's agricultural sector was already in decline, and a market glut was causing huge problems. A banana farmer might harvest 500 kilos of bananas, yet the marketing cooperative, needing to keep market prices at a target level, could only buy 50 kilos. The rest would simply be dumped on the loading dock at the marketing cooperative and left there to rot.
加上當時台灣農業已經開始走下坡，滯銷的情形一如今天，往往蕉農採收了五百公斤，合作社在維持市場價格的原則下卻只能給予五十公斤的配額，其餘就棄置在集貨場裡，任由它們熟爛敗壞。
