I'm not trying to be pedantic. The tax code is a mess. Simply saying you'd raise taxes on folks making more than a million of taxable income a year doesn't really say very much.
Something like an elimination of capital gains for startup investors and an increase to 35% of gains made over $5 Million per year would at least have some meat to it. Heck, just come up with a number. 20% rates good enough?
How can I evaluate "fair" based on that statement? Could you? I could make assumptions -- such as the definition of "taxable income" staying the same or perhaps the capital gains tax matching the income tax rate, but then I'm arguing with myself, because I'm adding detail that wasn't present.
Nobody needs a 30-page whitepaper. A couple of paragraphs with specifics isn't too much to ask. After all, it's the core of his argument.
