Like it or not, we can't cut enough of our spending to redress the deficit much less retire the national debt. Practically all the budget is spent on military, social security and medicare. These aren't very elastic. So, if you are proposing overhauling these programs to avoid tax increases, then maybe it will work but I'm likely to oppose that. This makes tax increases inevitable.
Sanders, in my opinion, proposed a graduated taxation scale that distributed the increases fairly and it will affect me. Everybody else is kicking the deficit can down the road. By not addressing the deficit, they only make things worse. Do I approve of this increase? Because I think an increase is inevitable, I support the one candidate that is honest about what has to be done. That said, the law will be written in congress and the devil is in the details. I might change my mind once the sausage is stuffed.
