No matter how you cut it, "taxes fund civilization". All of those things you want the nation to fund collectively (and I agree that many things are vastly more efficient to fund collectively) require taxing and then spending said tax revenues.
I'm not disagreeing or trying to be pedantic. I actually agree that there are adjustments that ought to be made to the overall national budget including less expenditure on military infrastructure and elective military campaigns. But I think the whole "but not tax and spend" thing is a cliche at this point because everyone has different priorities and opinions on what counts as "important" and what constitutes wasteful "tax and spend".
Every non-office-holding Democrat I know would go for it. The problem is that it's political suicide to actually suggest it, because most people don't realize how exorbitant our military spending actually is, so voting for a cut means you go on record as anti-military. That's not an easy rap to beat.
It's one of those downsides to democracy. No one has the power to just do it.
I am still trying to find an "ism" that resembles my views: spend money on roads, borders, police, education, social services, and healthcare; cut spending on the military, drop the second amendment, and step away from being the world police. Oh, and in the next 10-20 years spend about $500b/year on solving global warming. Then leave social issues the hell alone, such that as long as people are not directly harming each other, leave them the hell alone.
Sort of a mix of libertarian (socially liberal, fiscally conservative), with democratic ideas for healthcare (100% covered single payer, very good safety net for poor, unemployed), and the green party's concern for the environment. Oh and find me a politician brave enough to say something about the gun situation in the US.
