The left wants to spend other people's money.
The right wants to squeeze more efficiencies from wasteful government spending.
Take your pick.
While I agree that many see it this way or seem to find themselves in one camp or the other; I very much disagree with this 2 camps theology existing (not your describing of it).
I don't see why the two can't and shouldn't meet; I know they do in people like me.
My signature line is real; I am fiscally conservative (oppose deficits, prefer a government focus its energies, dislike corporate welfare, like efficient programs); but I am socialist, I support robust, expanded, universal healthcare, affordable/free, high-quality public education, a good pension system and high employment standards.
I had a discussion with a long-time friend who thinks he's a conservative, just before Christmas; He was sure he opposed high taxes and wanted them lower and so on.
I pointed out to him, with 3 kids, all school aged, he was receiving $39,000 in free public school tuition from government every year; never mind a National Child Benefit cheque well in excess of $10,000 per year. I pointed out to him he received more back from those 2 programs alone than he paid in taxes in a year, by a substantial margin.
That he'd have to sell his house if he had to pay out of pocket for those things.
That if he wasn't paying for them, in so far as he was getting more back than he was putting in; that I was the one subsidizing him (along with most others here); and the one in a higher tax bracket; he seemed amazed that if we cut taxes, he'd be poorer, while people better off than he would get the majority of the benefit.

Such myopia is not limited to 'The right'; ask any lefty how they would feel about their pre-teen daughter being out next to the needle-exchange/safe-use facility; or how much more they would really like to pay in taxes, for programs or services they might not benefit from............when they actually see the bill.........their mind often opens as well.
Funnily enough I don't so much advocate for a middle-ground, as an open-mind, and people looking at the evidence; and deciding where it takes policy/their vote from there.
There's room to understand that government can't do everything without deciding it should do nothing or less or only just about what it does now.
There's room to expect more of government, and better of government while understanding some of that should come from using existing dollars more wisely.
It's about finding the most effective ways to do things.
We don't need to reinvent the wheel, many cities/states/provinces/countries share our challenges, and many have found effective solutions.
While collectively they almost certainly require higher taxes that what we currently pay; that number isn't as high as many fear; and a surprising amount can be done if one spends dollars more wisely.
