I don't even want to link the second winner, but he is very connected in Saudi Arabia. Let's just leave it there.
I would point out that most kids with Robert’s access to resources would be smoking pot and playing Xbox, just like their poorer brethren. As someone without his resources competing at a science fair like him I feel absolutely no disadvantage and am impressed with his achievements. I ended up borrowing equipment from school rather than owning it but still had it. But I also wasn’t cool enough to find any pot.
In Robert's case there are highly motivated parents and a motivated student, but it's really about the starting point. Motivation is something that can be fostered.
Probably a $300-400 setup, which is not nothing, but well within reach of most families.
