"Capitalism is an accelerant for addictive behavior"
I'm not sure that what we have would be described as capitalism any more. If you buy FB stock, are they using that to build new machines that pay dividends over time?
You can make an analogy involving software, sure, but it really seems quite different to me. The way I think about it is this: if we all had amnesia and forgot that company XYZ existed, would it still have any value? Under traditional capitalism, yes, they would just need to advertise a bit and rebuild their customer base. But FB and google would be worth close to zero no matter how much software they have.
