ProPublica’s report does not suggest those billionaires broke the law and calculates the “true tax” not on income, but on wealth, which for the very rich is a much bigger number, since unrealized gains aren’t taxed.
There's advantages to running your own business and being very successful. I get tax advantages and I'm able to write off stuff my employees can't. But at the same time, I work a hell of a lot harder than the average person with a 9-5 job. I'm sure some of my employees dislike the fact I live in a nice house, drive a nice car etc. But I treat them well and I'm in a position to pay them above minimum wage and give them bonuses. I did however work damn hard to get to where I am. I worked several jobs to put myself through school and saved up to start a small business, which has grown over the years. Nothing was ever handed to me.
Do people really want to live in a society where the Government tells people how much money they can make? And if you make above a certain amount, you have to give it back and they'll hand it to the less fortunate?
