The consequence of not studying logic is that most people are like diodes. Recently, "Youth" has become popular, and the Bilibili commentary denies the current situation, wanting to return to the past and receiving many responses. With the economy declining, many people are feeling sad, and many believe that returning to that era would be better. A typical diode, dissatisfied with the status quo, believes that the opposing side must be good; the black-and-white dialectics harm people. To be honest, no matter how bad the current situation is, at least there is no worry about food and clothing. In that era, even eating and drinking were significant problems. As someone born in the 90s, it was hard to have a meat meal as a child, probably once a month, and new clothes were only available during the New Year. Every winter, the clothing was thin, and my hands and feet would freeze and crack. This was still the life about 20 years after the reform and opening up. The living standards compared to the 60s and 70s had already improved significantly, yet life was still so hard. One can imagine how tough that era was. If you still can't understand, go ask the elderly how their lives were back then. Don't be swayed by online narratives; the experience of not being able to eat enough or stay warm is far worse than what we face now by a hundred times.
