Few...more?

I don't get "Few investments are more consistent with all of our values and few are more sound." Would you please rephrase it for me?

It seems to me that it conveys the meaning "no other investments are more consistent with all of our values and are more sound." But this understanding is not clear as a bell at all.

Context:

And we invest in global health as a clear and direct expression of our compassion. Millions die every year simply because they lack access to very simple interventions, like bed nets, or vitamin-fortified food, or oral rehydration therapy. As a nation and a people, we cannot, we must not, accept those senseless deaths. It’s just not in our DNA. That’s why Americans frequently report that they support their tax dollars going to global health programs – not because of what the money can do for us, but because of what it can and does do for others. Few investments are more consistent with all of our values and few are more sound. Global health is a prime example of how investing our resources strategically can have an immediate and lasting impact on people, communities, and countries.
