I agree that some education spending does go into a black whole, but don’t forget that you studied at a State School. Where would you be without it?
Also, the point that was made earlier is mainly about scientific research and development. It’s about those things companies and buyers don’t yet see a market or profit. In addition to NASA another example would be the ARPA.
I get you’re point about letting workers keep what they’ve earned, and I am a fan, but a great society takes care of those that can’t help themselves. And that is another reason why central planning is necessary. It’s all in the execution, my friend.
