I'm rich & this is a lie. When politicians lower my taxes, I don't create additional jobs (only demand does that). I simply save that money
Trickle-down economics has been repeatedly debunked yet conservatives lie to you so they can give their wealthy overlords more tax cuts
If you want to help the poor, then lower taxes on the rich. What helps the poor is a productive economy that makes goods and services more abundant and less expensive, while creating employment opportunities. The capital investment that makes that possible comes from the rich.
