Our water systems - pipes are being used that were put into the ground sometimes over 100 years ago. Lead pipes feeding water from those water mains. Sewer piping that is as old as the water pipe. Water treatment plants and sewer treatment plants are held together with duct tape and chewing gum. Public schools that have been ignored so charter schools and sometimes religious operated schools can take public money.
The projects identified above, if addressed, would put far more people to work that on highways and bridges. Also, highway and bridge work provide for the highest profit margins of all construction work. The average road/bridge contractor will see about 15%-17% profit off of each job. A mechanical contractor (piping of all types, heating/cooling). electrical contractors, and general building contractors will see about 5%-8% profit from a job. That means more people (the workers) get more of the money put into the jobs. More people with more money will spend that money. Every dollar spent in a local economy turns over an average of six times.
Time for fair taxation.
