That's not a waste of education. There's no such thing as a waste of education. Maybe her experiences at Stanford reinforced her desire to do this, or strengthened her ability to make sacrifices.

There's more to education than making money. For one, if she didn't have that education, you wouldn't be talking about her.

Oh there most certainly is such a thing. Dining at a host home in the Phillippines while on a medical mission, we were introduced to the daughter of the family, as 'Dr'. Oh, what do you practice? Oh I don't practice says the daughter, as if it would be beneath her.

Now, there are precious few slots in that country for medical education. Such that exist are supported by the nation and the people directly and indirectly through taxes. One of those slots was 'wasted' on this human being, who's degree was an ornament on her wall. In a country where medical treatment is a privilege of the wealthy (thus the medical mission).

So pardon me if I regard education as a sacred trust, to be exercised to the best of your ability. Anything less is, at best, an affordable affectation. At worst, a moral failing and a crime against society.

A Stanford education is an asset to a human. A human is not a vessel with which to apply a Stanford eduction to the world.

It's also not like Wall St jobs have trouble filling positions. Charities do have trouble filling skilled positions.
