Ehh, I hope you realize how silly this is. The whole point of capitalism is that it's greatly flawed and it's not always fair, but it's the best damn system we have. If someone makes 10 times as much as someone else, they didn't work anywhere close to 10 times as hard. Part of pitching in is contributing to something, even if it doesn't relate to you.
When you were younger, you might have remembered having to clean up a mess (such as in preschool), even if you didn't contribute to it at all. Well, why is that fair? Because, if you're in the same situation, someone else might clean up the mess that you should clean up. I don't have any children, but I still pay taxes on education. And I'm happy to do it, because I recognize the value of children, and I hope to have some of my someday.
You speak about us all contributing to the country collectively, but that doesn't mean we can pick and choose what we want to pay for. This isn't some utopian capitalist system, we have to make due with what we have. A flat tax wouldn't make everyone put forward the same effort. People aren't robots, and they don't have jerk reactions. Flat taxes don't work due to simple rules of mathematics. Once you get to the higher levels of wealth, the percentages from a flat tax just aren't good enough. They don't need that extra money, and they got all that money from the work of other people. I don't have anything against this, but they shouldn't be complaining that they have to sacrifice slightly more of their vast wealth.
