I'd like to get a deeper take on this if anyone has any numbers to back it up. To me it "feels" like the last 2 decades of easy money and lack of investment into building entrepreneurship as a whole has led to a place where theres a lot of good money chasing two few deals or bad investments. That is to say the growth machine is responding to bad inputs over the last 25 years. To make matters worse there are only 2 possible solutions to any problem now: Technology or Regulation. These are hot takes/ observations though. I'd love to know what the average retirement is built out of, what its return has been. What has happened Entrepreneurship over the same time, and what has happened to VC/hedge fund returns in the last 10 years. If anyone has deeper expertise I would love to learn more.
