Infrastructure repair is not a gov't prority now as "social projects" are getting all the attention. And, previously it was war. What about real American problems?
Scary program recently on cable TV about our collapsing national infrastructure and how unconcerned our public officials are about spending the necessary money on it to avert obvious coming disasters. We now have, in this country, more money spent on ridiculous and worthless gov't BS such as innumerable politician's "fact finding"(free, fun world travel at taxpayer's expense) trips around the world than is being spent on repairing our critically damaged national infrastructure. Gov't response..."we do what we think is most important". Sure it does, like only "showing" concern after many people are killed, as with that bridge collapse in Minnesota. And, all it really cares about then is publicity damage control.
Thus, don't expect any great things in this area to be done by our gov't to lift MTW and its industry during Obama's tenure. Only a recovering economy will help with that.
