Beggars.

So, this saying, "IF wishes were hourses, the beggars would ride." I never got that.

Seriously. If wishes were horses, all them hungry beggars would eat horse meat. They would sell them and use the coin to buy food, but that many horses would make horses worthless. In fact, the world would be crowded beyond belief and quickly stink of rotting horse corpses, what with all the wishes men discontent with their condition make.

The onky thing it would accomplish is to serve as a lesson to men to be satisfied, but one too late as all mankind would promptly be wiped off the fact of the earth by horse overpopulation, the one death they didn't see coming for us.
