... likely to run into the solid wall of upper middle-class resistance, even those that simply require a slightly higher tax bill...
What are the unintended consequences of this slightly higher tax bill? Does this writer not know of the Laffer Curve? The top 20% already pay the vast majority of income taxes in the United States And now he suggests they should pay more? Why not instead reprioritize spending, including cuts to programs that are proven not to work?
The "War on Poverty" has not resulted in any significant change to US poverty rates yet money is still spent on those programs. Farm subsidies, social security and Medicare and Medicaid fraud and abuse and the defense department's propensity to bleed money-- there are many areas that can and should be addressed before simply raising taxes.
And what about college cost inflation? College expenses have risen more dramatically than health costs. Could the influx of easy public money and loans have something to do with it? Look at the cartel's controlling textbooks and scientific journals! We lose our collective minds over Uber surge pricing but say nothing about $200 textbooks that were often written by professors working for public institutions. In universities you have countless Provosts and vice Provosts who pretty much add no value. You have administrators who simply administer other administrators. It's a racket of which the mafia could be proud. Adjunct professors barely scrape by while the "Director of Residental Student Diverisity Affairs" makes six figures. Many on the left like to complain about CEO pay yet let academia have a free pass to hand out titles and six figure non-teaching jobs out like candy -- all on the backs of students and indirectly, the taxpayer. If we want to expand educational access then the universities ought to start with themselves: cut the waste, lower the price. But they won't do that; the "liberals" in charge of universities actually perpetuate the educational inequality they purport to oppose. It certainly isn't conservatives in the Ivy League that maintain legacy based admissions or $80,000 per year price tags.
The problem isn't that taxes are too low, it's that government does a bad job when it comes to budgeting and fiscal policy.
I am not opposed to "left wing" proposals as much as I am opposed to "raising taxes and redistributing wealth" as the only means presented as the way to accomplish those proposals.
Zero-based budgeting would be a good start. Then every year the government can better allocate money rather than just continually adding to whatever the previous year's expenditures happen to have been.
