Very interesting post. However comparing to countries is not an apples to apples comparison. Its fairer to compare to other tech enterprises and other social media platforms.
The thing is that early founders of successful tech enterprises (such as Facebook and Google) always have a very large share even compared to people who BUY in later.
People who don't buy in and are just users of Facebook and Google have ZERO ownership of the platform - in fact their economic share is negative because they are the product.
