Companies being the sole arbiters of OTA "Upgrades" and DRM "purchases".

Mass Surveillance.

Resort fees, especially in Las Vegas.

Toilet paper

Car rental - I'm 95% sure I don't need any of those extra insurances but due to pressure and fear tactics (you do want to be covered if x happens, right?), it's hard to know in the moment.

most cheap things that fall apart after a short time

Video game trailers

Credit cards and everything to do with the debt trap.

In the US - - taxes.

Things used to be a lot simpler & cheaper in the US, but then we passed the War Revenue Act in 1917 which drastically increased the budget & helped to pay for the war. They probably saw all that money rolling in & got greedy. What was initially designed as a war-time fund raising effort is now just standard taxation, it has gotten worse, and the people being born & working & dying nowadays don't know anything different.

The government wastes so much money. Whose money? They don't have any money! They're wasting our money, that they extract from us via taxation.

We are financially raped into the ground, not allowed to enjoy the fruits of our own labor.
