"world had only two people[..]possible[..]that both values can increase[..]everyone can get more wealth without anyone loosing wealth."
yes, but we're not living in caves anymore. we're living in a hyper competitive world.
every cm² an this planet belongs to somebody..the top 1% own most of the wealth..there's no such thing anymore as free land / free resources..
if person A earns 1 dollar, you're taking it away from person B. ones value increases and the others decreases..
