That's the fundamental problem with "trickle down" economics, it assumes the economy is supply constrained when it is more commonly demand constrained.
I was of the understanding that most orthodox schools of economics fundamentally view demand as infinite. Supply-siders hope to meet demand by increasing supply, lowering prices, and making more goods available to those with fewer resources. Policy-wise, this is achieved through production subsidies, fewer regulations, and tax cuts.
Their opponents (demand-siders?) hope to increase access to goods by increasing the purchasing power of consumers. Policies like social safety nets, public education, and tax increases on the investor class promote this goal.
