Scale matters. Information inequality was inevitable.
Free trade led to growing concentrations of economic power and rising economic inequality. We also have information inequality to go with it, and because information transfer is much lower cost than trade, information inequality will be much higher and power more concentrated (social media stocks should thus be valued higher than companies which make real things)
Not sure the article understands that inequality is inherent in the structure of the web.
If you wanted to reduce inequaliy there are two options: 1. redistribution 2. raising the 'transaction' costs
In economics we know what those look like:
1. progressive taxation and a welfare state 2. legislation to raise environmental standards, increase minimum wages, etc.
What's the equivalent of a social welfare state and higher minimum wage when it comes to information?
Another way of looking at this is in terms of externalities: free social media generates both positive (connecting with old friends) and negative externalities (fake news, election mischief, etc).
One way of internalising both would be for Facbook to charge users. That is never going to happen. Carbon credits and the like make polluters internalise the costs that society would otherwise incur. So, what kind of legislation (and it will have to be legislation) would get social media companies to be pay for the negative externalities?
