I believe the point of OT was: it doesn’t matter that much if you view stocks as long-term investments. At its all-time high in 2007 the S&P was roughly at 1,500 points. It returned to this value in 2013 I believe, and is now over 4,500. So in hindsight you could have easily just put all your money into a S&P ETF at its 2007 "all time high" and still would be doing great today.
