i noticed this morning on the news they are referencing it could be as bad as mount st. helen. trust me, that was a devastating impact to our state. i hope that all federal agencies are helping in whatever ways we can with hawaii's natural disaster. and thank her for also talking about the importance of net neutrality. i, too, come to the floor to defend the open internet because it is a pro-consumer, pro-innovation rule that we have to build on because it's worth the 7% of our g.d.p. and 6.9 million jobs. that is what the internet economy is. net neutrality that we are fighting for today has four bright lines, four lines that help businesses, helps consumers, and helps our internet economy grow. they are, don't block content, don't throttle content -- that is, don't slow it downs, don't create paid prioritization. that's like saying in the burger king ad, if you want the next whopper available, pay more. i think they did a pretty good example of if you had every business operating that way. the fourth is transparency. know exactly what you're getting charged for. the obama era
