Is compound interest a false proposition? No, but it is very difficult.

Four necessary conditions for the compound interest principle to work:

1. A moderate amount of principal.

2. Appropriate positive returns.

3. Sufficient duration, for example, you said thirty years. But how many thirty years are there in a lifetime?

4. Continuity, positive returns cannot be interrupted. This is very, very difficult.

Can you count the number of people in the world who meet the above conditions on one hand? ​ ​​​
