If you are asking this seriously, trickle-down economics is an absurd nonsense theory, there are no examples of it.
Also, money changing hands is not what creates wealth, and those security details would be just an artificially maintained middle-class that can never be large.
If it had a definition, it wouldn't be nonsense, would it?
"Trickle down economics" is a rhetoric instrument by which people try to convince the public that taxing poor people and fiscally spending in rich people will increase the poor people's quality of life.
[…] It’s a nonsensical economical theory, with no definition on the context of economics.
Hrm, if it has no definition in the context of economics, how could you know argue that, by its definition, it is a nonsensical economic theory? That seems to fail modus ponens.
