If the utilitarians took themselves even a little bit seriously, they'd be proposing redistribution of all but a $1M annual stipend from every one of our planet's top ten (10) richest people.
That's about $1T; a $1000 windfall for every human alive (assuming some shrinkage in distribution).
Billions of people live on $3 a day or less
Imagine the aggregate utility of giving half of the world a YEAR'S PAY.
