The development of space isn't about exploration. King Ferdinand and Queen Isabella didn't sponsor Columbus so that he could go exploring. They wanted him to find a trade route to the east and to claim undiscovered lands for Spain. Columbus was an explorer, but the people who wrote the check had other motives.
If we rely on government to continue its snail paced investment in the development of space transportation, and to restrict private development in innovative fields, our economy and our education system will continue to founder. Increasing the rate of space transportation to a point where we can see the results of our work will cause a natural interest in innovation, and stimulate a desire for education and economic development in related fields, much as it did in the 60's.
The Dept of Ed is bigger than NASA. It has ruined our education system. Putting some DOE money into the development of space transportation and economic development of the solar system will cause students to compete for educations with backgrounds in math and science. Government won't have to step in and put bandaids on a failing methodology.
Instead of government stepping into everything, burying people under the bureaucracy of the bandaid mentality, and destroying the attitudes of leaders and innovators, a practical application of space development can be one of the methods by which we once again look to the future with a sense of hope and accomplishment.
