Whether some think it's leaky, or that it is a melting ice cube or ultrasound money is irrelevant. Despite or with support from opinions of others, it is ultimately you who makes the decision where to store your value.
Only time can say if you've made a good decision, as not one person can predict the future, and likewise you must suffer or enjoy the consequences of your decision.
The irony is that the whole message is that it doesn't matter if you disagree or disagree, only the quality of the decisions you apply your framework towards. Time will reward those who take time to understand this stuff and punish those who don't. Liking the message is entirely besides the point.
Depends on the laborer. There's no law of nature that grants me the ability to make good financial decisions as an award for my labor. The ability to manage risk is not an ability that gets unlocked once you accumulate enough money to invest. Now, I have to both work hard to make money, and gamble to protect my future.
