The first part of that statement shows ignorance of big crowds. If you have ever been in a large crowd you know that when the crowd starts moving, you have no choice, you go with it. If there is something, or someone, on the ground you walk over it because you have absolutely no choice in the matter. I've been in dangerous crowd situations twice in my life, once at a rock concert and once at a post soccer game party. It's very scary and I have no problem at all understanding how people get trampled or crushed. It has nothing to with people not caring about their fellow man. I have to agree with the second part, I doubt any instructions would help once it gets past the tipping point.

I did some work at years ago at Wallops Flight Facility. Whenever a untested or otherwise dubious rocket was scheduled to launch there would be a "will it clear the sea wall" pool. I'm sure there was heavy action on this one.

The same can (and has) been said to all nations that spend money on space travel.

From "Whitey on the Moon" (1969) by The Last Poets:

Taxes takin' my whole damn check,
Junkies makin' me a nervous wreck,
The price of food is goin' up,
As if all that shit wasn't enough
A rat done bit my sister Nell
(and Whitey's on the moon)
Her face an' arm began to swell.
(but Whitey's on the moon)
Was all that money I made last year
(for Whitey on the moon?)
How come there ain't no money here?
(Whitey's on the moon!)...
