Net neutrality has been around for 2 years, and the Internet seemed to be doing just fine before that.
The amount of hysteria over net neutrality is insane. ISPs have very little incentive to actually fuck over customers/content providers. The root of the problem is the fact that there is a monopoly in certain zones on ISPs. However, that number is growing smaller each year, and we already have laws in effect to provide protection against monopolistic practices.
Net neutrality just allows the US government to intervene in ISP practices, making this less efficient and more costly on the ISPs who have been pretty hammered by things like Netflix changing the scale of the Internet greatly. Also it allows the US government to have more of a say into what is 'fair' and 'unfair'. So you've essentially shifted your trust from the ISP to the US government.
Now I'm not against most of net neutrality, in fact I support it for the most part. There's just consequences of being labelled at Title II service that are not in line with what everyone is claiming for net neutrality. Ones that hurt both large and small ISPs, which at the end of the day will cost consumers either way. The barrier to entry to becoming an ISP is so gigantically high, that anything that hurts small ISPs is exponentially worse for the market.
ISPs have gotten so much shit when the real fact is that 20 years ago, the internet was mostly static documents. Nowadays we have 4K streaming and sites like Netflix have completely shattered the traditional throughput of the Internet, which ISPs have had to build around.
