There is a big difference between 'needs' and 'wants'.

I'll defend the argument no one 'needs' more than 1.5 mill per year.

I agree with you greed is endless and lots of people want more and will rationalize their hoarding while others, often in their own communities, suffer.

No one really "needs" anything. You can live perfectly well on minimum wage. But really, you could survive perfectly well as a slave. Infact, the world is content for you to die and get nothing. All "need" is "want". All you deserve is what you have leverage for.
