The Ponzi Factor is the most comprehensive research ever compiled on the negative-sum nature of capital gains (non-dividend stocks). The book is not a perspective or an opinion. It is a proof that is based on definition, logic, and it is supported by observable facts and history.
The simple truth is profits from buying and selling stocks come from other investors who are buying and selling stocks. When someone buys low and sells high, another sucker is also buying high and needs to sell for even higher. Companies like Google, Amazon, and Tesla never pay their shareholders. Their investors profits are dependent on the inflow of money from new investors, which by definition, is how a Ponzi scheme works.
