Only young and naive guy believe in high risk high return
In the world wars, young and naive people go to battle field and fight each other to death, they take risk to protect the war that they can never win, while they’re being manipulate by the other group of elite who do not like to take such risk. These elite tell the young people to take the risk despite they know it’s risky and they don’t want take the risk but want someone else to take such risk. Many people died and sacrificed in the war that can’t be won. The elite do not take the risk, not only they didn’t take risk they also profit a lot from the war, for the people who love to advocate high risk high return, NOPE you’re wrong, they take no risk while they can make the maximum profit that those of you who take risk can only dream of.
There is actually more to it than being naive. One thing that an older investor will tell you is that younger people have one of the most important assets when it comes to finances - they have time. That allows them to make mistakes and recover much easier than someone later in life who has less room for error. Naturally there is also a learning curve where people have to make and learn from their own (hopefully small) mistakes to become wiser.
