Net Neutrality repeal will have a long tail effect. It will cause the economy to slow as people have less disposable income, it will cause the cost of starting new sites to skyrocket as people choose plans that limit their access. It will make paying municipal bills more expensive. Repealing Net Neutrality is in effect a tax increase on American consumers and businesses, no more no less. The only real question is how far it will move the needle and realistically that depends on how expensive Comcast decides to make it. They have a monopoly and they fully intend to exploit it as far as they can, regardless of the detriment to the internet or consumers. Personally I hope they go full evil right off the bat. Were the American consumer in any way shape or form intelligent or in possession of a spine they wouldn't put up with this, but as it is, we're feeling what it was like when Rome started to decline.
