The problem is not the cake, it's the oven.

这个句子出自经济学人，加上上下文是：

Mexico’s shoddy procedures bedevil infrastructure projects of all descriptions, including line 12 of Mexico City’s metro and a planned drainage tunnel for the capital. “The problem is not the cake, it’s the oven,” says Mariana Campos of México Evalúa, a think-tank.

关于The problem is not the cake, it's the oven 这句，我在词典中找到的翻译是“问题不在于蛋糕，而在于烤箱”，这个明显只是直译，如果结合原文翻译，我个人想法是翻译为 “问题不是怎么分蛋糕，而在于怎么将蛋糕做大”，因为中文也有用“分蛋糕”来说明“利益分配”的例子，不知各位老师觉得这样翻译是否恰当？非常感谢。
