This guy has some of it right. But the caveat is that you just have to find a way to invest and hold assets that appreciate in value at some rate higher than overall inflation, otherwise you're at best treading water and taxes will erode your stored value over time.
Just like many have realized, it's not about picking a winning stock, it's about picking a stock that does better than the market as a whole which is, on average, always going up and to the right.
