We all started RC racing.
I read his wiki page. His dad bought him a racing cart for Christmas when he was 6. His dad had nice IT job and started his own computer company. His brother also races professionally.
You don’t start racing being poor. At the very least his family was middle class. But definitely not rags to riches. More like less rich to filthy rich. His dad only had to pay for his cart racing for 4-5 years before the big support money came in from McLaren at age 13.
So yes he was fast but he was never poor. They say humble upbringings, but humble compared to someone who grew up in Monaco is a pretty damn good start.
