Not So Funny
"Trickle-down economics" and the "trickle-down theory"
are terms in United States politics to refer to the idea
that tax breaks or other economic benefits
provided by government to businesses and
upper income levels will benefit poorer members of society by improving
the economy as a whole. ..
"Mr. David Stockman has said that supply-side economics was merely a cover
for the trickle-down approach to economic policy
—what an older and less elegant generation called the horse-and-sparrow theory:
'If you feed the horse enough oats, some will pass through to the road for the sparrows.'"
