Wikipedia says that.
"Trickle-down economics" and "the trickle-down theory" are terms used in United States politics to refer to the idea that tax breaks or other economic benefits provided by government to businesses and the wealthy will benefit poorer members of society by improving the economy as a whole.[1]
I think " suck up theory (siphon over theory)" is better.
Rich people is good at sucking up (siphoning over ) money from poor people.
So at first. Poor people had better had money . then they spend money soon and Rich people sucks up (siphon over ) money soon. Most people can get money.
