What sucks is that this is all hypothetical. But if I'm already contributing, then I can tell them what to contribute as well!!!!!!!!!You're wrong. If you want to be entirely responsible for yourself, fine... Build your own house and power it with energy you create.
Otherwise... every single member of society you benefit from has the right to tell you what contribute to it. This includes things more complex than a simple flat tax.
Don't tell me what morals I should have. A government should be run on ethics, not morals. If I have money I inherited from my family, or if I earned it through my good efforts, then its MY money. I should be asked no more than anyone else. I pay my taxes, I abide by the law. Now, should I wish to help people out of the goodness of my own heart, then that's my right as well. I contribute to society by being a consumer in the economy and paying my taxes to the government.
So no. I am not wrong.
