net neutrality works perfectly fine. websites such as netflix, audible, steam and whatever kids use today pay the creators of the product. but websites such as the pirate bay which steals content and puts them up for download at no cost mean that the content creator gets nothing.
thats not the problem of not having net neutrality
the simplest example is not having it allows network companies to see "oh, you're using netflix, im sorry but we will have to throttle your network speed due to high load unless you pay us an extra $10 a month to access netflix at normal/faster speeds," or charge netflix extra to send its data fast to consumers, which still get passed on to consumers
and its a very real threat cause if companies could do this they would cause its easy extra $$ for heavy traffic. right now they cant though
