Really, common sense elementary school math is weak?
Wrong, it's super simple. The US can't spend more than you make indefinitely. The idea that by 2020 the world will spend 1/5th of it's GDP buying US debt to finance our out of control spending is laughable. It's not going to happen.
If we wanted to do simple, common sense math we could look at the income distribution and to the math ourselves.
You're arguing from a faulty premise. There's no one or no part of the gov't distributing money, income or wealth. The gov't doesn't create wealth or income. It doesn't hand it out to the well off. The gov't is a parasite on the economy, not the engine of the economy. The well off didn't steal the money from the poor. As such the whole idea that the income and wealth gap between people isn't fair is utterly and completely bogus. But, class warfare plays pretty well.
Wrong? It's not like he doesn't have an army of accountants and analysts, not to mention better data than you or I to take into consideration.
Where the evidence of this better data and an army of accountant?
In addition to the fact that this has been one of the major causes that he devotes his (not inconsiderable) resources towards. That would make him an authority on the subject in my opinion.
You can't tax & spend your way out of debt. The idea that such a result is possible is preposterous regardless of how many accountants you have. Buffet acts like we've got a small cut and just need a bandaid (slight tweaks to the tax code) to make it all better when we've lost a limb and have serious bleeding going on.
Having a massive net worth doesn't make you right. Earning the largest net worth in the world yourself makes you an authority in matters of finance. I don't see him complimenting the state of government, just wanting to plug some holes in the tax system. Considering he is lobbying for change, equating him with the status quo seems odd.
You're completely missing the point. The changes he's lobbying for are like slowly using a 5 gallon bucket to empty a swimming pool in a torrential downpour and thinking it'll be empty in no time.
