You're welcome.
They've used extremely low (depressed) interest rates to dissuade people from saving and also from saving in traditional bank accounts. So the vast majority of Americans have their retirement plans stuck in stock-based 401Ks. That's done by design so that when the time comes they can wipe out the savings of most Americans.
Any retirement portfolio needs to be diversified --- "don't put all your eggs in one basket" --- and have a certain percentage in low-yield investments such as Treasurys --- with the level of risk you think you can endure. Someone who puts all of their 401(k) in high-yield, aggressive stocks can lose much of everything they ever worked for. Don't be that person. As a rule of thumb, the older you are, the less risky your portfolio should be. I've already gotten my hair mussed by the 25% I have in stocks, but it could be worse. Markets always trend upwards.
Of course, if all of this is a prelude to the Apocalypse, then all bets are off, but at the end of days, it wouldn't matter anymore.
