Imagine every road in America was a toll road. Now, imagine that every shipping company who used those roads tacked on the cost of tolls to goods. Now, imagine the cost in time from having to go through toll lanes. All this adds up to extremely inefficient and uncompetitive American firms. If everything was a user fee system, the costs of doing business in America would be astronomical.
While I dislike corporate welfare, the millions in taxation at the federal and state level that goes into building capital improvements for corporations does allow them to compete on the international market and provide jobs for Americans.
