Tin Pan Alley's Influence on songwriters

Tin Pan Alley must have been an interesting place to work, with all of the creative writers so close to each other. Do you believe working in Tin Pan Alley really influenced the writers to create their greatest hits? I wonder if any of the songwriters worked together on songs to make popular hits? Tin Pan Alley music on the rise during the great depression I feel had a major impact on the lives of americans, giving them inspiration, and the ability to climb out of the recession. How many songwriters from the Tin Pan Alley do you think played there music in public areas for exposure? I feel I wouldn't be able to have a 9 to 5 job trying to think of lyrics and melodies to a song. Does anyone want that kind of high risk, high reward job?
