Every disadvantaged nation, and perhaps our own nation, becomes our patient.

Imagine if disadvantaged students could receive equal access to advanced science and math classes

And the thing about states like Arkansas and Tennessee is that they're both very rural, and they are educationally impoverished.

But it always leaves behind that 10 percent or more that is most disadvantaged or unlucky.

I was that someone else, because I was small and in a disadvantaged position at that moment.

The lesson is that our patient the world, and the disadvantaged of the world that patient deserves our compassion.

And for me that means spending time thinking and talking about the poor, the disadvantaged, those who will never get to TED.

We could be providing early childhood care for economically disadvantaged and otherwise troubled kids, and we could be doing it for free.

So, if we are to be the world's healer, every disadvantaged person in this world including in the United States becomes our patient.

But the thing is that for every 15,000 dollars that we spend intervening in the lives of economically and otherwise disadvantaged kids in those earlier chapters, we save 80,000 dollars in crime related costs down the road.

We could be providing special schools, at both the high school level and the middle school level, but even in K 5, that target economically and otherwise disadvantaged kids, and particularly kids who have had exposure to the juvenile justice system.

And yet, the median age of diagnosis in this country is still about five years, and in disadvantaged populations, the populations that don't have access to clinical services, rural populations, minorities, the age of diagnosis is later still, which is almost as if I were to tell you that we are condemning those communities to have individuals with autism whose condition is going to be more severe.
