I bet the Japanese felt the same way 20 years ago when Japan was the second largest economy in the world... let me give you a great quote from a so so book:
"When you went to medical school did you ever want to graduate with a C average?” The doctor said, “No.” Vandergrift replied, “Do you want to send your kids to a C school?” He said, “No.” Vandergrift countered, “Then why are you doing that with your money? The S&P is an average. It’s an average of the 500 largest companies in the United States. It’s an average. It’s a C index. Why would you want to invest to get average returns?”
That's a generic anecdotal story that exhorts people to try to do better than average that could've been used as a response to anything. I'm not even sure that you're reading my posts other than seeing "pro-indexing" and trotting out random active investing arguments.
Reference class forecasting. Have you heard of it? Do you know that it reliably improves the accuracy of your predictions? What makes you a better investor than everyone else trying to beat the market?
