# Wealth Creation: Where does the money come from?

I'm trying to better understand wealth creation– let's use trade as an example.

I've bought a cup for \$2 and sold it for \$10. We've "created some new wealth" there– but without a net increase in actual dollars that exist, how has more wealth been created? Am I not just taking \\$10 that already existed from someone who perhaps made it at their day job? Who's boss in turn took it from the sale of a bagel? Aren't these dollars that already exist?

How does this boil down into actual new wealth and money?

• If you sell the cup at a profit, you did take the dollars from the buyer. Retailers normally sell goods to consumers at a higher price than they themselves pay. That activity is not typically described as “wealth creation,” it’s just normal commercial activity. What wealth do you see being created? – Brian Romanchuk Nov 15 '18 at 21:40
• @BrianRomanchuk It adds to GDP. This was a good answer: economics.stackexchange.com/questions/17890/… – aroooo Nov 15 '18 at 21:51
