profit of enterprise, n.All

Profit of enterprise (n.) appears ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠to the active capitalist as the fruit of his own activity, while interest appears as the fruit of mere property — idle capital that does not 'work'.

Profit of enterprise (n.) presents ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠surplus-value as its opposite: the capitalist seems to get it not because he works as a capitalist but because, apart from being a capitalist, he also works.
