This specific policy mostly benefits Amazon and its shareholders.

If you think this exists for your benefit, please feel free to bask in the illusion of your wild runaway success.

But it doesn’t. If it was true prices in the EU would be lower. But the EU is by far and large more expensive, even after accounting for VAT.

The issue is that those policies drive prices up globally, and the article touches on that exact point. Sellers have to absorb Amazon's fees while being required to keep the same price. As a result, their sales outside of Amazon have to factor in those expenses, which drives up prices for those products in general. Even if someone could sell that product at a lower price outside of Amazon, they won't lowball themselves and would rather improve their own margins.

Then, in the EU, you have to factor in fluctuating currency exchange rates and sales tax/VAT set individually by each country. This is another issue altogether.

Americans generally hold SPY which makes them Amazon shareholders.
