The theory of tragic growth deeply studies the situation in immiserizing growth. Productivity is developing rapidly, but poverty is increasing. One of them is the difference in value caused by different productive forces in different demands. For example, the terms of trade between agricultural sector and industrial sector will be unfavorable to agriculture with the continuous development of economy. Twenty-five years ago, a farmer could produce 65,438+000 bales of rice every year, but urban workers of the same quality could produce a bicycle every year. At that time, farmers could exchange 10 bag of rice for a bicycle, so farmers had 90 bags of rice left. But after 25 years, urban workers with the same quality can produce five motorcycles a year, but farmers can still produce 100 packs of rice a year. But farmers have to trade 90 packs of rice for a motorcycle, so farmers only have 10 packs of rice left. Twenty-five years ago, urban workers created bicycles worth 10 packs of rice a year, and 25 years later, urban workers can create motorcycles worth 5*90 = 450 packs of rice a year. The key problem is that the added value of agricultural products is too low, while the added value of industrial products will increase with the continuous development of economy, from the value of 10 package of rice to the value of 450 packages of rice. Therefore, farmers exchange agricultural products with no added value for industrial products with increasing added value, which leads to the deterioration of trading conditions between agricultural and industrial sectors, thus making the countryside poorer and poorer.

Therefore, greatness lies in the progress of science and technology and the development of society, but we must see the anomalies, which is the real all-round development.
