请英语高手帮忙解析一个句子
From the middle-class family perspective,much of this,understandably,looks far less like an opportunity to exercise more financial responsibility,and a good deal more like a frightening acceleration of the wholesale shift of financial risk onto their already overhurdened shoulders.
此句中第3行的"a good deal"在这里是什么意思,在句中起什么作用?
