Understanding the Author's Purpose in Urban Development

In the following passage, the author discusses the implications of urban development on community dynamics:

'As cities expand, the fabric of neighborhoods often changes, resulting in a blend of cultures and ideas. However, this rapid growth can also lead to the displacement of long-term residents, causing a rift in the community that once thrived on shared history and mutual support. The juxtaposition of new businesses and old homes creates a landscape where nostalgia meets innovation, leaving many to wonder if progress is worth the cost of community.'
