May I humbly recommend the excellent The Proper Role of Government, by Ezra Taft Benson.
He was a former President of the LDS Church, but the essay is well worth the read anyway. There's a bit of LDS scripture in there, but you can easily skip over it if you like.
My bad, I posed the question poorly.
It should have been, “What percentage of your money are you willing to give to the government, that they may do the things you wish? Roads, schools, etc.”
Once we agree on that, the next question is how we get it, as a percentage of GDP - it really doesn’t matter, as long as there is a limit.
Then the libs can argue how to spend it - I really don’t care. If they don’t fund roads, I will make a fortune with my 4X4.
But where we have failed, is in asking the first question.
