I wonder how it affects a BogleHead strategy to retirement. If the Sp500 (VOO, or VTI, VT) is less and less representative of the U.S. market, there is a case to be made that it's becoming disconnected more and more of the "real" economy. This is kind of undermining BogleHead strategy to just buy the full market as the full market is less and less accessible.
