text: Pipelines have economics measured in decades, are profitable in every price scenario, relatively very cheap to decommission vs their construction cost, allows customers to realize a better price for their product in different markets and will increase the governments revenues on both royalties and taxes. 
  
  Please explain which pipeline companies have gone bankrupt in North America forcing tax payers to pick up the tab and how it is unlikely they will be properly taxed. They are merely a transportation alternative similar to shipping, rail, air, or tractor trailer, or are they taxed improperly as well?
