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.
زیرا پدر-- یکی از پدران انقلاب صنعتی، آدام اسمیت-- متقاعد شده بود که انسان  بطور طبیعی تنبل هست، و کاری نمی‌کند مگرآنکه که شما آن کار را برای آنها ارزشمند کنید، و روشی که شما آن را ارزشمند می‌کنید توسط تشویق آنها و توسط پاداش دادن به آنها هست.
