> I don't know why so many feel the need to reduce the effort, skill, and ingenuity of these founders and builders as if them building a Berkshire, Amazon, or Tesla was a given.

It was not a given, but these people are serial coin-toss winners and lazy observers claim they found a way to have an edge in the 50:50 coin toss odds.

In reality if you take a sample of 8 billion people somebody is bound to record 10,000 consecutive coin toss wins , and not because they consciously found a way to crack the coin toss process, but purely because of luck and law of large numbers

The initial hand over of money from rich parents is just the very start of wins in the long series of coin toss wins.
