Price gouging. Because supply and demand is a thing. In Capitalism.
Bear in mind, if it wasn't for massive subsidies, that, and everything else everyone buys in America would cost a lot more. Heck even gold.
The largest gold mine in the world is some mountain in Nevada. They're literally turning it into a crater. Thing is, the gold is so diffuse, it can't even be detected with an electron microscope. Even though it's gold, it's so expensive digging out all the tons of ore, trucking it out in trucks with wheels that are like a couple of stories high, processing it for that microscopic amount per ton, it just isn't profitable. So the whole thing is subsidized by taxpayers, because the company that owns it can't afford to do it on their own. We pay for them to profit off of gold.
Years before all of this, decades even, the price of gas in Europe was DOUBLE what it is in America. A slice of pizza costs $8 worth Kronurs in Iceland. This is over a decade ago. Americans didn't get fat because food is expensive. Americans got fat because their taxes go to help all these companies lower their own costs, all the way to the supermarket. That's still happening, but due to an increase in demand after the pandemic started to slow down, they started jacking prices up. First to make up for their losses in 2020, then because people keep letting themselves get ripped off anyways because you never know how much more it might cost next week.
