Even if we follow Obama & MSM explanation that behind every successful business there’s a list of government’s involvements,it doesn’t explain why only certain business are successful while others are not. Everyone has access to roads, bridges, etc. But only few made it. The best we can make out of that argument is such assistance was necessary condition to success, while individual’s efforts are the sufficient condition for it. Even this way of seeing is already a stretch.
Those roads and bridges were built with bonds and debt. That entire business model requires future profits from taxation to eventually pay the bonds or debt. So in areas where the local tax base has collapsed (Detroit, California Cities (4), etc.) the municipalities that issued the bonds and acquired the debt have gone bankrupt. Since some of the places that went bust, had decent roads and bridges, do not think the roads and bridges are the main issue.
