No it's really not the point. Hindsight investing is always 100% accurate.
Or that the stock market is "Las Vegas", a "gamble".
Over time and over the index, the results are proven. It's not hindsight, like say you wish you could have been an early inverstor in just one stock.
You have less memory than an Atari 400. You always forget I claimed over a short period of time Wall Street is a gamble, and the chips are stacked against the average dummy, who is not getting in on some new IPO and doesn't have access to the algorithms and speed the big boys do. Poker has better odds than day trading or trying to pick individual stocks, and the really lucrative games are not open to the grandma investor. Over 40 or 50 years is an entirely different argument.
