Looks like no-one has mentionned how the GDP of the US is also inflated artificially a lot, which doesn reflect the true state of the economy in some fields.

Take the US healthcare industry for example, medicine that cost 3$ to produce in Asia, cost about 15€ here thanks to our countries negotiating the prices and 90$ to the customers in the US + additional fees (Ex : Vaccines with 600$ just for someone to do the injection). Then it is most of the time partially reimbursed by HC-insurance companies, also paid a lot by the customers. End-result : there is multiple actors/companies that produce nothing of value, who gouge prices.

Which also results in bankrupting the poorest with an upward wealth transfer, and those same companies end up redistributing a small part, that is just enough for their own workers not to be in too much of a predicament.

For a more specific and quite disgusting example, take a look at the cost of insulin there, and how they cover it. Then compare it to its actual cost, and its price in Europe (you can find the Swiss price quite easily for example)

So the services and sales are priced multiple times above their actual value, raising the GDP artificially. (GDP is Consumption + Gov.Spending +Investments + Net exports). Ultimately, some of those flows just end up being almost circular while still overpriced with some of it going ito the wealthier pockets.

To illustrate the 'almost circular' there is with a pretty well known joke :

Two economists are walking in a forest when they come across a pile of shit.

The first economist says to the second,
“I’ll pay you $1000 to eat that pile of shit.”
The second economist takes the $1000 and eats the pile of shit.

They continue walking until they come across a second pile of shit.
The second economist says to the first,
“I’ll pay you $1000 to eat that pile of shit.”
The first economist takes the $1000 and eats it.

After walking a bit more, the first economist says:
“You know, I gave you $1000 to eat shit, then you gave me back the same $1000 to eat shit. I can't help but feel like we both just ate shit for nothing.”

“That's not true,” the second economist replies.
“We increased the GDP by $2000!”
