Why isn't the Marvel Universe a supertech paradise?

Between Iron Man (Arc Reactor technology) and Ant Man (he could easily build a space elevator, among other things), how has humanity not turned the Earth into a supertech paradise, then conquered the Universe?

Sure, guys like Thanos might prove to be a problem... until 999999999999 Iron Man suits made out of Uru simultaneously blast him in the face.

Reality intervenes. Set aside the products of this "supertech." Let's look at mundane tech. There is enough available "fresh" water, and enough available food produce, to supply every individual on the planet.

Yet people starve and suffice to drink contaminated water, or die of thirst. Why?

A question of the ages. There lacks the infrastructure to deliver these commodities to everyone on the planet. There lacks the desire. There lacks the awareness.

Why should "supertech" follow any different laws? Why should we expect these superheros to behave any differently?

Yes, we attribute to them a higher level of morality, but they are still subject to the same base emotions.

You have beings with nigh unlimited stamina that think they are bettering the world by punching people instead of, say, cranking a generator to provide free energy.

You have multiple PhD scientists developing transportation to alternate dimensions to satisify curiosity, rather than eliminate gridlock.

But the real question is, would supertech really make this a paradise? They've developed weapons capable of destroying the world. Do we want these passed out to everyone?
