It's called "supply side" economics. I means that, in theory, by providing corporate and wealthy tax breaks, it frees up more capital to create jobs and increase the number of goods available for purchase.

When faced with either a lack of manufacturing capability or a lack of available investment capital, supply side economics works. It can generate jobs and goods to sell at home to the newly employed and overseas.

Unfortunately, the US has a glut of manufacturing capability now. Plants are closed and sitting empty, so tax breaks for the weathly simply go into savings, not back into the economy, or maybe to those jobs overseas.

Some folks, however, just don't get the idea that there is no one-size-fits-all economic plan and keep harping on the same note.
