True.. but in capitalism, if you earned something, it's yours... if you make two sandwiches for your son, does that mean you have to give one to the community? Why does the same apply to money?
I understand that taxation is necessary. I also understand that people like to keep what they earn. I draw this line at half... and I would draw that same line for the wealthiest (who bend current tax law to pay far less than half) to the poorest, who would recieve a basic income (along with everyone else) to subset the half that they earn and get to keep.
I feel this is the heart of the issue, that people think of money and wealth as "mine" vs. "not mine." It's the whole American individualism at play, where it's you vs. everyone else, where you getting richer is a Good Thing, even if (or maybe especially if) it increases the gap between you and others.
Whereas a much healthier mindset is "mine" vs. "ours." You have money that belongs to you and you have money that belongs to your community. This community can be a neighborhood, a city, a state or even a country. Once you flip this mental switch, you realize that the taxes you pay are not really taken away from you, but rather shared with everyone in your community (of which you are a part).
