Meaning: born into wealth2 or great luck. Use examples.
Rewrite 1: born with a silver dollar under his tongue
Rewrite 2: conceived in a mansion and delivered in a Rolls-Royce
Rewrite 3: gave birth to a bouncing baby billionaire
Rewrite 4: never had to worry from the moment he came out of the womb

Comment: The third rewrite is stretching the metaphor in that it doesn’t talk about the person being born but rather to the mother giving birth. However, it still works to convey the life of privilege the baby is born into.
