It would suck.
If you could be sure that none of the peopel were people you loved or even liked, then maybe.
But even then it would suck.
It would be cool if I was driving down a street and some guys were unloading an armored truck, and, POOF! They disappeared?
But not really because the whole value of money would get screwy. THe survivors would get all the disspearee's shit, as well as their money. SO everyone would immediately (or almost immediately) become about 150% richer. You'd have all this money and all this stuff, but let's say you wanted to buy something really fancy and/or custom made, there would be 60% less skilled craftsmen who could make that thing, so the demand would bi higher and the price would be higher....
ugh this is making my head spin
