The current extreme inequality leads to the grotesque situation that some few people have so much money, that they cannot spend more than small amounts of it at a time, without making it worthless.

They have so much more money than there are people in the world or things to buy, that they have to hoard the money. They must keep the _velocity of money_ down, or it would dissolve into nothing because the market would become flooded with their cash.

That's why central banks can print so much:
*People aren't spending what is being printed.*
