=== SUMMARY ===
- The post questions whether BRK.B has underperformed the S&P 500 (SPY) over the past 23 years on a cumulative basis.
- The author is skeptical of long-term "buy and hold" justifications, citing past performance as a counterargument.
- Quality assessment: This is a low-effort query with no data, analysis, or original research — it is noise, not a well-researched DD.
