Not quite. That's simply trade and it was found in the world, including in the market, long before the rise of capitalism.
Private trade for profit is capitalism. Capitalism was borne out of trade.
If the trade is capitalism, how can capitalism have been born out of the trade?
You really think barter and trade didn't exist before the rise of the capitalist system?
I've had this discussion with a few conservatives at the work place. Surprisingly, they didn't really understand all that Capitalism entailed..and described their economic utopia as being a place where the gold standard was put into place, and barter the principle means of trade.
