Earlier quoted context omitted.
We have nuclear tech because Manhattan project, because WWII(and because they were scientists coming from Europe that were scare of Hitler). It took a tremendous amount of money and sacrifice to get there. No, Manhattan project took trivial amount of money by today's standard. It costed less than the rounding error in typically given federal budget figures for past few decades.
It cost 2 billion in 1939. That’s over 20 billion in today’s dollars. That’s about the same as NASA’s annual budget.
Truly, we are easily able to afford projects like Manhattan and Apollo today, it's just we aren't able to pull them off anymore.
