If I had to guess what the most profitable organization in the world is, I think I'd put my money on NASA.

Wait, what?

In the US, people swoon at profits and prophets (Jesus), I'll kick this off with a quote from Jesus, Mark 8:36 “For what shall it profit a man, if he shall gain the whole world, and lose his own soul?”

Even Jesus knew there's more to this than money.

It sounds like a good way to deal with negative externalities is to make entities responsible for them pay for correcting for them. But that's hard to do. If the US forced all of its polluting companies to stop polluting, then non-US companies might have a competitive edge.

4/*
We have positive externalities, too. If you're an American who never went to school, you're still probably better off than someone in Mozambique because the people around you went to school.

The positive externality of education is to boost the entire economy.

5/*
Or there's the positive externality of the police: their mere existence can lower crime rates. You're less likely to be a victim of crime, *even if you didn't pay your taxes.*

This is called the 'free rider problem' of public goods.

6/*
In the "free rider" problem, if people realize they can benefit without paying, they often try not to pay, through means both legal and otherwise. This is why, almost by definition, anything which produces a positive externality tends to be underfunded.

7/*
What sort of things produce significant positive externalities and are constantly under-funded?

* Education (understand your work)
* Health care (able to perform your work)
* Public transportation (able to get to your work)

But they all contribute massively to the economy.

Let's get back to NASA. Strictly speaking, they're a government agency—not a state-owned enterprise—so profit isn't quite the same, but what about externalities? We can't ignore the pollution. Rockets produce unusually large levels of pollution, but

But actually, NASA hasn't launched enough rockets for it to (yet) be to blame, and they did so before we understood the issue. Still, they laid the foundation for it, so we can't ignore it. But for the purposes of this thread, I'll ignore it anyway.

10/*
But what about the positive externalities? That's easy. Think of the technological boon NASA has been. Let's consider a short list of things NASA has developed directly, or contributed to the development of.

11/*
Air quality monitors used in smokestacks
Better structural analysis technologies
Energy efficient insulation
Freeze-dried food

Not enough for you?

12/*
Machinery lubricants
Many new medical techniques
New hydroponics techniques
Scratch resistant lenses

Still need more?

13/*
Semiconductors
Smoke detectors
Solar energy
Water purification systems
Weather forecasting

See where I'm going with this?

14/*
NASA has, and will continue to be, one of the greatest powerhouses for national profit the US has ever known. Think about those massive benefits we've been receiving for *decades* because of NASA.

15/*
And because NASA will continue to do cutting-edge research, they will continue to produce those technological marvels which can boost the US economy far beyond where it currently is.

18/*
There's also this 2013 Tauri Group study on "NASA Socio-Economic Impacts". They found that for every dollar spent on NASA, $2.60 was returned to the US economy.

Not too shabby for an incredibly inspirational organization.

As much as people bash on NASA, and yes, they do have some issues, they have done so much for us that we take for granted. And if Musk can get to Mars, or Bezos to the moon, it's because NASA paved the way.
