Discussion - what is the difference between public policy, social policy

Discussion

1. Briefly, in your own words, what is the difference between public policy, social policy, and social welfare policy? 

2. An example of one such challenge was industrial jobs pulling more people to cities, which created circumstances of overcrowding, poverty, and disease. As we are now moving from an Industrial economy to an Information economy, dominated by technology-focused jobs and industries, what new challenges are we seeing/can we expect to see in the future? How will our role as social workers need to change to face these new challenges?
