The nation’s public transit industry faces some of its greatest challenges: ridership has been declining; infrastructure is deteriorating; rivals such as Uber and Lyft are taking transit customers. Does transit have a future? Yes, says Art Guzzetti: transit is a vital part of American cities and will continue to be so for many years to come. No, says Randal O’Toole: transit is doomed to extinction, and politicians and transit agencies should find a path toward winding it down instead of trying to expand it.
