Oxfam has told us all that 8 people have as much wealth as the bottom 50% of humanity and this is an outrage, Something Must Be Done. OK, so, let us think about what must be done then. The most obvious point being that we should reverse the outrage. Take all the money off the rich people and give it to the poor people. At which point that 50% of humanity would each get $100 or so.
This is not actually a solution to anything at all, is it? Thus the original problem being complained of is not a problem, is not an outrage and does not require that something be done.
