Really? I would bet that most people don't hold their views on government spending based on anything more than a gut feeling and what the political party they support and associated media tell them.
I believe this because time and time again we see surveys that show random groups of people have a very VERY poor idea of what the actual state the economy is in, what the history of the economy is, who increased the national debt, who decreased it and when, what inflation is actually at, how to plan for current and future interest rates and house prices, who can control energy prices, etc. And most importantly (to me anyway) how wealth and income is actually distributed. These are mostly indisputable facts that we can all look up but somehow don't.
So yeah I think we as a group are mostly misguided most of the time.
