“You get what you pay for.” Not always.
The Apollo mission cost roughly $25 billion.
For that, we got Tang and a bag of rocks.

We won't mention the huge leap in medical equipment nor the miniaturization of chips that now make computer that fit in your pocket and are unbelievably more powerful that any in those days. You'll notice that Tang was made in 1957 by General foods not NASA

Another much longer list - see above list

These types of lists are a huge stretch of wishful thinking.

As an example, here is a history of LASIK, from The LASIK Vision Institute:

I appreciate the correction about Tang predating the Apollo mission.

That leaves $24 billion for a bag of rocks and bragging rights for the moon landing.
