Ug, you just struck a pet peeve of mine.
By definition, anything "zero-sum" means whatever is lost by one, is gained by another. Therefore for every winner, there is a loser. This means 50% win, and 50% (at least on a value basis) *if* trading was a zero sum game. It is not. Poker is an example of zero-sum.
The stock market is 110% sum game lets say. People get rewarded when they put their money in things that make life better for the average person. This is economic growth and rewards everyone. Win/win.
I make plows lets say. These plows allow farmers to farm with twice the efficiency. So now whatever was getting done before, gets down now in half the time. Or given the same amount of work, double the output.
Assuming double output, as long as I charge less than half his total output, the farmer will be better off than he was before given the same work. Lets say I say "charge" 25% of his increased output for a plow, with which I can trade for materials to make 2 more plows. Or I can make one more plow, and eat the profit. This is what profit actually is. Establishing a new and better way of doing things. Getting more outputs from the same inputs.
More modern example:
Even though an Iphone costs $700, the map features saves me time getting lost, money buying maps, the calls allow me to contact people real time instead of walking to their house or mailing a letter. All these increased efficiencies and savings are worth lets say $1000 to me. So I'm better off with the phone than without, even after spending $700. It literally improves my life. Since it only costs $400 to manufacture, Apple profits $300. What that $300 really is though, is increased productivity from me for the benefit of the rest of the world. It saves me 10 hours in a year. I use that 10 hours to make 10 extra cars. That makes the world better, because now 10 ppl can drive who couldn't before which in turn makes me $1000 more income.
Because Apple was clever, I'm better off, they're better off, and the rest of the world is (marginally) better off because there is more "stuff".
Conversely I can sell my rights to the profit and control of the business decisions. This is the business, or a fraction of it is the stock. Provided what that company makes is of more value than the inputs, and provides value to someone else in excess of the cost, this is where value is literally created out of the blue. This is why the stock market (and economy as a whole) is not zero-sum.
