Was Alain Prost born into a rich family?

Answer 1

No, not especially. His father was a furniture-maker, so it was a fairly humble background. He bought his first kart (old and very used) with his own money, and relied on prize money and prize drives from his results to pay for moving up the motor racing pyramid.
