Actually, the 30s showed that rewriting the constitution and heavy government intervention can make a self-stabilizing economy become a crippled one beat into submission by seizure of gold for ultimate government power.
They showed that too, but our economy is still not going to take off till interest rates are high enough to make it worthwhile.
" I object to anything that is likely to result in profitable spinoffs with a decade"
That makes no sense whatsoever.
Yes, it does. If a profit can be turned in 10 years, then private enterprise can and should finance it.
"Right now we have 3 private companies working on commercial orbital flight. There is no way private enterprise could have pioneered in space flight"
That is correct, but only because the government already did it.
No, because without the government proving the concept, demonstrating the possibility of profit and shortening the time line to profitability from 40 years to a few years, private enterprise would never have put up the money.
