You have your point, but the advantage for rich people is they can enroll and be at prestigious schools/universities that will enhance
their knowledge to be more competitive.
Unlike with poor people who need to be above average to have that opportunity to enroll as scholar in any high-class school who
offered scholarships.
And some politicians and some non-profit organizations who also offers scholarship which also requiring above average grades.
This is an advantage that the rich can give their children, but they do it not because they can just do it, but precisely because they understand the importance of a good education. They understand that their fortune will then be inherited by their children, and only competent management will help to preserve and increase the fortune in order to also pass it on to the next generations.
I am sure that each of us would like to preserve what we are creating now, perhaps for many of us who are trying to create a good fortune in the first generation, it is important that the fruits of our work be preserved by our children, this should be thought of today.
