Trickle-down is akin to old Toryism. It only works if you have a paternalistic vibe towards the “little people.”

Which is also bad, so…

Money doesn’t trickle down. It does, in fact, trickle UP.

The best way to support a healthy economy is to give money to the people who will promptly spend it: The poor.

In other words, the ethical thing to do with the money is ALSO the most effective.
