Profit

Profit ,somehow, must have been a "conversion" of something. For ancient traders, it was the conversion from a dangerous journey - therefore the producer & consumer have their benefit out of it - may we call it from braveness ? A kind of adding something into it ! (Dutch was one of the great explorer/traders at their times).

But profit can be a simply conversion of other's loss, a kind that is not "taking something ! " - you can just squeeze (or abuse it until zero) your employee wages to increase your margin.

I'd prefer to the definition "to work is to contribute !" so it shouldn't be just to "collect money" - from a less to more to even more !

As in a "zero sum" business -which "gambling" is one of the example, "to win" means a somebody's losses minus "facilitator" fee & cost. It means to grow by use others shrunk - the more it grow the more the other end loss.

So in contribution (working) , there is always something to be converted - I'd prefer it to be "sweat" & "creativity" - along with other element such sincerity , integrity , dedication etc. If no one have ever tried baldy try to think about "gravity law" , there'll be no aircraft which is in their turn contribute to even larger "world development !"
