The whole point of any trade is that I give you something that I value less, but you value more. I have 10,000 apples just lying around. You have $10,000 in you

The whole point of any trade is that I give you something that I value less, but you value more. I have 10,000 apples just lying around. You have $10,000 in your bank account. So you pay me a dollar and I give you an apple. To you, $1 was more than fair for the apple, because you were hungry for apples. To me, 1 less apple for 1 more dollar was also more than fair, because I want to buy other things. So when Amazon pays 100k to an engineer, it is not a zero sum transaction. To the engineer, 100k was worth more than his time. To Amazon, the work done by the engineer in that time was worth more than 100k. Value was created. How much value? I don't know, but definitely greater than zero.
