public investment to what end? that's what's not common sense at all. what form is the public investment? are we trying to create new industries? put everyone on social welfare?
To what end? To establish a healthy society where people are free to explore and take risks.
Itβs not that complicated. Remove the risk of failure by giving people money for food, a place to live, an education, and protect their health.
There is a reason that many successful founders came from money. That kind acted as a safety net that allowed them to bet big. Not everyone with money goes on to establish a big business but the rate of success is far higher for those with money.
