Well, saw a comment on the news last night as to the management of this regarding the refineries (exxon etc) , the insurance companies (who actually rule the planet ) and retailers and ordinary food/basics etc.
To summarise, simply.
"This is too big to expect companies, or the government to have much effect on, the costs WILL be passed on to consumers."
My emphasis, but you get the picture.
If its correct that the louisiana port system supplies even a fraction of the goods distrobution network in the states, well...thats not good . It will take a month or 2, even with military assistance to clean up this mess.
