To cover current Federal expenders they would have to raise taxes to 24% of GDP. That is just federal taxes. The only other time it has been that high in the past was during WWII. Why do we need 6% of GDP more money ever since Obama was elected than we needed any other time in the past 50 years? Were we doing do bad before? Look what is happening to countries like Greece when they take such a large percentage of GDP out of their economies. The economy buckles and collapses and incomes for everyone plummet to where everyone suffers gravely. It would be one thing if there were no examples of this going on around us to observe so that we could be warned about what happens but that is not the case. Anyone who wants to know can see clearly what happens because there are examples of it happening right now. But you have to be willing to look and observe objectively. I know that may be asking a lot for some but really, it doesn't take all that much effort to just look at what is going on and recognize it for what it is.
