When you look at the eye-watering amount of money that Zuckerberg has spent on false starts in the past ~10 years, it makes you wonder whether capitalism truly does produce the most efficient allocation of resources.
Granted, a lot of that money created jobs for white collar workers, which feeds into other parts of the economy. But is it really more efficient to allocate those resources toward enriching a small group of Alexandr Wangs than allocating it toward projects like infrastructure, modernizing energy production, building housing, etc?
