I think the poor would suffer the most under a revenue tax regime, unless the increased tax take were thrown into welfare or basic income. The compound effect of a revenue tax along a supply chain would result in huge inflation in products with long supply chains (food and consumer goods) and relatively little effect on things like services and high margin businesses.
