I don't entirely agree either. I was just expanding on the idea. However, when there is no employee, such as in the example you gave, there is also no profit. What you have called profit is actually your wage. Do I make a profit when I go to work for a company? No, I earn a wage.

It's a company which makes the profit. If you started a company and sold the tool for $500 and the company paid you $500 then there is no more profit for the company. If the company paid you $250, only then can they claim to have made $250 profit.

Hence, profits are nothing more than unpaid wages.
