I notice that only two are considered "variable" in this article: founder and employee.
The fact is, VCs/Investors are becoming less needed than they were 10-20 years ago. Why wouldn't it be logical for their stake to take a hit for the money they put in?
A third option also exists...Investor total share goes down. I personally believe we will see this more in the future.
However, it would possibly be in the VC industry's interest to invest a team willing to create a startup that begins as a town (but owns enough surrounding land to grow into a city) that puts engineers first. Google effectively does this, but it bounded by geography and therefore can't control the cost of living for its employees. It engages with the rest of the world through capitalism while practicing some degree of socialism within the company.
This would allow the VC industry to risk far less while still affording the founders and employees a very high quality of life.
Honestly, I'm surprised we haven't seen Peter Thiel and Co actually bankroll a project like this himself since he is such a proponent of ideas like this.
