In what ways did the major industrial nations of the west become more responsive to the needs and interests of working people?

Industrialization went hand in hand with democratic institutions and respect for private property. To the extent working people constituted a unified block of voters, they had to be listened to. 

Now, let me ask you a question: What does your question really ask? That is to say, what do you mean by "the major industrial nations of the west"? In what way are they different from the "working people" who live in them? Or, do you think that all John D. Rockefeller did was sit around all day and let money flow into his pocket like honey from a pot? Guys like E.H. Harriman worked very, very hard. So, does your question really make any sense?
