The problem isn't the percentage of spend of GDP. The Baltic / European states spend quite a bit more than us in terms of total GDP percentage.... they also get more back in revenue (through more taxes for things like public healthcare). The problem really is the difference between the two numbers which is a measure of the net lending / borrowing that a country does as a percentage of GDP......
There are very few developed nations in the list of lenders right now. Most of them are petrol states that have government control of energy revenues.
In terms of net borrowing rating we're better than the UK, India and China, but worse than a handful of others.
Our government revenue as a percentage of GDP is under that of Japan, Canada, the UK, Germany, Australia, Spain, The Netherlands, France, Italy, Sweden, etc... etc... etc... On one hand that's good for our businesses..... on the other hand it's basically our government borrowing to subsidize the wealth of businesses and private citizens.... (mainly those who would pay the most taxes if they were raised to comparable levels. )
