Nasa was not a pressing need. The world would have been fine if we had never gone to the moon. yes it had benefits but you do not know that we would not have invented Tang without it.
That's the thing about EXPLORATION... you have to actually do it to find out if there is great benefit.
You usually strike me as Conservative but a realist. But on this you are simply small minded. Could not, were not THE EXACT SAME THINGS said about those who wanted to search for the New World. Did not backward people complain about that in exactly the same way? But Spain spent the money and sponsored Mr. Columbus. Worked out pretty well with government support on that EXPLORATION.
And you are also missing the many vast military projects like satellites that were pushed into R&D and deployment way... way... way before there was a commercial use.
I could go on with numerous other examples.
We had roads before the fed existed. We would have had great roads too. like we do today, as soon as asphalt was invented. People would have been motivated by profit to build roads just like there were before the fed and still are today. I live in a community with private roads and there are no toll gates.
You simply live in the land of coulda been revisionist history my friend. At the time that project was seen as simply too big to be done. Sure if government were not allowed to sponsor it, it would of happened at some point tiny bit by tiny bit. But it was needed THEN. And that the entire country, all citizens benefited so greatly from it being done THEN is not even in dispute.
Vaccines were invented privately and are produced privately and the only part that gov plays is to distribute them and to force people to take them. We could have done without that.
You simply have no basis in fact here my friend. The government pours tons on money into modern vaccine R&D so that the private sector & universities will come up with advancements and life saving treatments decades faster than without. We saw how much it helped with polio and government help was relatively late to the game on that one. Since then the government has been investing in life saving medical advancements earlier with unprecedented positive results.
The remarkable pace of the Salk polio vaccine's approval, production, and national distribution required an enormous collaborative effort among the federal government, state governments, vaccine manufacturers, public health agencies, physicians, and other groups. We can trace the multiple roles of the Eisenhower administration, both in public and behind-the-scenes, as it coordinated the national roll-out of the vaccine.
