Because the father -- one of the fathers of the Industrial Revolution, Adam Smith -- was convinced that human beings were by their very natures lazy, and wouldn't do anything unless you made it worth their while, and the way you made it worth their while was by incentivizing, by giving them rewards.
Protože otec – jednomu z otců průmyslové revoluce, Adam Smith byl přesvědčen, že lidské  bytosti byly ze své podstaty líné a neudělali by nic, pokud  by se jim to nevyplatilo, a jediný způsob, aby  se jim to vyplatilo, byly pobídky, odměňování.
