There will not be consensus...
Some folks see the space program as a huge waste of money and post those sentiments using their Tapatalk, PC, Ipad, or whatever - which technology traces directly from the race to the Moon and the need for smaller computing machines...
Later in the day they will visit a friend in the ICU which exists primarily because of the space program and the need to remotely determine if an astronaut is alive or not...
Solar cell technology was driven by the need for making power in space...
The list of devices we consider indispensable is so voluminous I can't even begin... Do a search on it... A good article starts here:

And then, there are others that see our huge welfare society as the giant black hole sucking us down...
Currently (2011 statistics) 49% of the population (160 million) receives some form of benefit payment from the government...
Coincidentally 49% of adults of working age pay no Federal Income taxes...
(these two sets overlap but are not necessarily congruent)
That ONLY 50% of the working adults in this country financially support our society is not sustainable... It is not sustainable statistically... It is not sustainable as a social structure... It is not sustainable as a business model... And it is not sustainable ethically (regardless of your religious beliefs, or lack thereof)
20% of those paying taxes provide 70% of the governments annual income... Yet the current administration demonizes those people, calling them pejorative names such as 'rich', demonizing them, and accusing them of being cheats and criminals...
This is not sustainable either...
The analogue of that would be a business telling the 20% of it's customers who produce 70% of it's cash flow to go away because they are bad people..
