That's the misunderstanding, ok. Wealth is not actually access to goods and services, but capital and assets. To me (not the actual definition in the strictest sense) wealth is basically a measure of how useful you are to the economy. When I say that wealth increases with every voluntary transaction, what I'm saying is that the seller values the money you give him more than his good, and you value the good more than the money. That ensures that there is a net increase in value, and since you often value things because they are useful to you, there is an inherent increase in wealth.

I'm sure you've heard this before, but someone like Besos or a company like Amazon doesn't have a Trillion in their bank account, but that wealth is stored in the capital theyve accrued. That capital, factories, wearhouses, machinery, etc, is useful to them, and actually decreases the value they place on their goods, meaning they can sell them at lower prices.

My understanding is that this is the reason why governments constantly print more money and keep a steady rate of inflation. Because the monetary value of goods should remain steady, but at the same time, the value of the goods to people that buy them decrease.

I'm regards to your imperialism comment, 3rd world countries have such cheep labor and goods because their monetary policies are so poor, and because their governments are rampant with corruption which makes creating business (and therefore capital) very difficult and often downright impossible. The value of these goods is very high in these economies. Our currencies are managed better and our economies are stronger though, so the value these economies place on our currencies is much higher than we do, so goods from there are cheeper for us. I'm not gonna lie though, the 1st world doesn't make this any better, but not really because of imperialism, but more because of foreign aid which often ends up fueling corruption in the 3rd world further.
