‘Democracy’ is two wolves and a sheep voting on lunch!!
Indeed it is. The example I use in discussion can be applied to an individual household, class room, town, state, nation etc., using the most relevant example per the discussion.
Suppose the "poorest" 51% vote to take everything from the richest 49% and redistribute it among themselves? What's to stop them in a pure democracy? Of course, once you do that, there will be a completely new "poorest" 51% who will vote again, to take all the wealth, possessions, or even lives of the richest 49%.
Pure democracy is mob rule, and an inherently unstable state.
