Which one below is said to be even more severe about left-behind children?

China has 61 million so-called " left-behind children". Economists say this is the price of China’s modernization, and it could jeopardise the next generation of Chinese growth. Children educated in poor rural schools, without literate parents to help them, may be unable to fuel the new innovation-led growth that Beijing is aiming for. And the damage to Chinese society, to the family system and even to the psyche of the children involved could be even more severe, according to economists, government researchers and others who have studied the left-behind child phenomenon.
