I think a better description of supply-side economics would be to state that everyone gets tax cuts, and everyone benefits because of the resulting expansion in economic activity. Do the people with higher incomes get bigger savings in terms of absolute dollars? Yes, of course they do. But that's because they are the ones paying the taxes.Take a look at Reagan's "Trickle Down" theory as well. I don't think that worked the way it was expected to either. It basically said (and I'm grossly oversimplifying) that by giving tax breaks to the rich, the money would "trickle down" to poorer folks through better sales, a stronger economy, and raises and such. It did not do so. It wasn't based on Objectivism, but post-Trickle Down data did show that the most well-off people kept a lot of the additional profits that they received from the tax breaks for themselves and their higher-ups rather than letting them "Trickle Down" to middle-class America. I'd be interested to see how the data from this program might affect your theory. I'd have to admit that economics is one of my weaker subjects so I can't offer you more than a lead.
"Trickle down" is code for "I don't believe it".
