2020 Presidential candidate Sen Klobuchar wants to tax big tech companies' on data use

As privacy scandals mount at firms such as Facebook, Presidential candidate Sen Amy Klobuchar (D-MN) is positioning her data tax as a way to make technology companies think twice about how they share and profit from users’ data. But implementing such an idea might be difficult, experts noted. Taxing data means you have to know what such information is worth, for instance. Former Facebook employee Antonio García Martínez says data is often compared to oil, but that's a poor analogy because unlike oil that has a clear price, the ultimate value of data is unknown. Outside of using data to allow targeted advertising, it’s difficult to measure such information's value because that can change dramatically depending on the context.
