The simple act of just existing on this planet costs money. This alone is proof that we live on a prison planet. You need money just to have access to basic things like food, water and shelter. And everytime you get paid, the powers that be take some of that money (taxes) and and if you buy something, even property, they take some of that money too.
And you have no say about what they do with it, so some of your money ends up contributing to war and the killing of other human beings, and you have no choice over that. And if you wake up to how much of a prison all of this is, you can't even leave. If you try to “leave” this prison and you fail, they lock you up in a mental institution.
To live on this prison planet you basically have to sell your soul so you can afford to buy food to feed your body, which is basically a prison in itself, and if you question the idea of work your fellow prisoners call you lazy for not wanting to contribute to the system imprisoning them..
