AVAILABILITY OF CHEAP RAW MATERIALS
This requires:
ØMore efficient use of resources
ØSearching for additional known resources
ØSearching for substitute resources
ØSearching for new energy sources

*We are running low on many key natural resources, including minerals, energy, and water. We must find fresh sources on Earth or in orbit, as well as enhance conservation and substitution of resources.

* Industry requires cheap common materials to substitute for expensive imported materials, such as silicon fiber optics substituting for copper wires.

*Prosperity is a direct reflection of availability of energy. We need to invest in new, economically viable sources of  energy such as fusion energy, and perhaps solar power satellites. Fusion energy research is on the verge of break-even now.
