This is What “Always” Happens Before a Market Crash
This is investing 101, a very simplistic view of past crashes. He identifies four causes. However he is skating on the surface.
The fundamental cause of all crashes is stupid money.
Think of Social Security as "stupid money". Every two weeks a little money is skimmed off of every pay check in the country, put into this huge account. That is stupid money. The same is true of 401k and other retirement accounts.
Imagine most Americans want to invest the money in a way that it will grow without having to really know anything about how or why. This is why everyone scammed by Bernie Madoff was scammed.
You have two kinds of investors, predators and prey. The prey think they can simply graze on the grass in a big giant herd and they will be fine, don't need to know anything. The prey see these huge herds and plan how to eat them.
Here is what this video misses, in every market crash where his friends and family lost their bank account, their house, their investment, for every one thousand who lost thousands there was one person who made millions. People assume that since they didn't understand what was happening and what was about to happen no one else did either. That is not true, it might have been true for 99% of the people but not for 1%. They knew what was happening, it is basic human psychology. The fact that people are willing to invest in something without understanding it is the fundamental reason for all market crashes.
Suppose a man has two siblings, who are both married. Now all six people are employed, they have retirement accounts and between the six of them the accounts are worth $2 million. They have no idea what they are invested in, only that it is "diversified" and the broker recommended it, and hopefully when they retire it will be there for them. They could start a family business with that money. They could start a business that they fully understand, that they are fully involved in and that will also become an inheritance for their family. Why don't they? Simply because they have no faith in themselves. As a result their kids don't have a business they can inherit so they must also be employees and have 200k debt to some university. One day UPS or Google or META simply fires them despite their schooling and the thought that they had a really good job. On that day they discover they didn't have anything.
So then stupid money is really, at the root, faithless money.
