What problems did the Soviet Union's industrialization cause? What lessons can we learn from it?

Only paying attention to heavy industry leads to its extremely backward light industry and agriculture and unbalanced social development. The backwardness of light industry causes a serious shortage of people's living materials, and the backwardness of agriculture leads to a shortage of food. Lesson: National development needs to be combined with reality and balanced, and cannot be blindly promoted. (Maybe so, it's a temporary summary, please forgive me if it's not complete)
