The definition of profit
Is profit meaningful for work done in isolation?
There are so many definitions of the word profit, that I am not yet sure what we are talking about.
In the pure accounting sense of business, I think of profit as the difference between the price paid by the consumers and the costs paid by the owners.
From that perspective, if the owner of a fruit tree works to make sure the tree is productive, but eats all the fruit (does not sell any), is any profit created?
