The opposition to tax increases would drop significantly if any such were met with corresponding spending cuts. Every department could identify 1%-5% in waste that could be cut without affecting services. Heck, even eliminating baseline budgeting and making every program have to justify continued funding would help. Too many are on autopilot.The main problems are low tax revenue and the wealth and income gap. Of course.
As it stands right now, any tax increases would simply be met with even greater levels of spending that would quickly eliminate any temporary gain in revenue (until the taxpayers figured out how to get around the increases).
