Agreed. Would Apollo have acheived its mission without the small steps taken by Mercury and Gemini? Highly unlikely. It takes small steps to finally acheive a big goal.
And it's not safe? There will always be risks in exploring and getting to space. Car's are not completely safe, airplanes are not completely safe. However, there are people willing to risk their lives to go into space. If we use that excuse for not doing something, then we might as well just sit around all day only doing what's 'safe'.
And there has been over 30,000 secondary applications spun off of NASA products. The smoke detector? That's hasn't saved peoples lives? Was used by NASA before entering homes.
Human tissue simulator? Device that helps patients with chronic pain. Yeah, that's not helping people
Pacemaker?
Laser Angioplasty?
The list goes on and on.
Read some of these to learn about the benefits besides TANG or velcro.

So maybe we haven't gotten one huge revelation from exploring space, like curing AIDS's - different types of cancer - etc. But to say we're "pissing the money away"...
It reminds me of how before Apollo was launching there was this huge movement against the program for the exact same reasons. However, the head of NASA's administration *can't remember his name at this time* told the guy leading the movement (was for poverty in the US), that even if NASA was abolished and fund's were gone - the people would still not get that money. And then NASA was getting a lot more money than they are today
