Europeans, what is something that Americans have/do that makes no sense to you?

The way politicians and the political system nakedly serves the needs and interests of corporations and the wealthy, and not the average individual.

The way that the price you're quoted invariably gets bumped up by various taxes.

The insane system that is tipping, including the fact that a lot of workers are so underpaid that they rely on tips to get by.

The incessant adverts on TV for medical products, particularly prescription drugs.
