Laffer curve and many others advocate a zero capital gains rate. The increased aggregate supply would result in increased aggregate demand, hence the term "supply-side economics".

Additionally, the Laffer curve depends on the assumption that tax revenue is used to provide a public good that is separable in utility and separate from labor supply, which may not be true in practice. The Laffer curve as presented

According to Bremmer, a government's motivations differ dramatically depending on where they
