How would the money be well spent?
If the money is spent paying Google, Netflix, Verizon, or other engineers, we end up with newer infrastructure, better services, and the like. If it's spent building rockets to circle the moon, then we still pay this (not just "we pay it in taxes", but the labor is spent and the labor is compensated--we work and we exchange our time for this), and what do we receive?
Wasteful spending reduces the amount of stuff you receive for the work you do. That's true across an entire economy for obvious reasons (if half the farmers instead make war machines, half the food doesn't get made, and you pay for war machines that only go out to get blown up). What are we gaining by spending $23 billion here?
You cannot be serious... Do you have any idea what kinds of technology advancement NASA has been a primary driver of? The list is long, varied and many things invented for our space programs of the 1960-70's are ubiquitous now. Ever used Velcro? Ceramics? Digital cameras? Miniaturized solid state RF communications devices? Anything that depends on something in orbit (GPS, Most Syndicated Radio programs, most remote Sports TV coverage...). Need I go on?
One would expect a new space program would have similar benefits to humanity, consider it an infrastructure project. So YES, money well spent.
