Fred: Yay. I bought a house worth $200,000. Woohoo!
Government: Okay Fred. Gimme $5000 NOW.
Fred: WTF?
Government: Do you not get it? I said give me $5000 now, and you will do so every year you numbskull. It's called the "property tax".
If you don't, I will seize your house.
Fred: What???? But it is my property. Why are you forcibly taking away a part of it.
Government: Because you're my bitch.
