Moster网友的译文相当不错，可供你参考。唯独最后一句the child改为人称代词he更好。我在你译文基础上做最小的改动，更接近你的原翻译，也供你参考。

The researchers believe that the difference in child raising between differrent social classes is becoming greater, which is an omen of  the agravation of social inequality and will lead to profound consequencies. Different ways of child raising will put children on different paths of gowing and worsen their social-economic disparity, especially in the case that education is closely linked with income. During their growth youngers can learn skills that are needed for their success within their own social class, but will not necessarily acquire other skills.

1 这里的研究者应该是前文提到的一些研究者，属于特指，应加定冠词。believe用被动句没有道理，改为主动句。

2 建议使用difference between A and B in C这样的句型。

3 deepen与disparity不搭配，改为worsen。

4 take into account不可后接that从句，改为in the case that。

5 during介词短语移至句首，避免误读为定语从句的状语。

6 that needs应为that are needed.

7 would均改为will。研究者认为他们的反映的是真实情况，故用陈述语气。
