Eh, supply and demand. They're not paying that money for the food or the dj, but rather the location of Times Square.
My non-profit does the same on the 4th of July. A front row seat at the fireworks (and bbq, some entertainment) is sold for $125 pp, which is mostly a charitable donation.
I'll be at a tv-free location, so I won't be watching the ball drop myself, but it's always anti-climatic when I do.
