The Cantillon Effect is a phenomenon under an expansionist fiat currency system where those who receive newly minted currency are able to use the currency without immediate negative effect on the economy, but as the new money diffuses throughout the economy, prices are driven up, thus deteriorating the purchasing power of the money.[1][2][3]
Basically, those closest to the central banks are able to buy up assets, while the poor are left to suffer high inflation. The rising prices benefit the owners of the assets, and crush the wage-earning proletariat. This increasing class division can lead to rising populist sentiments, as was seen with Bernie and Trump in 2016.[4]
