Looking at your numbers or just social spending, it is increased 50% since 1990 as a portion of GDP. Real GDP adjusted for inflation itself has increased more than 3x since 1990. This means that us social spending in terms of inflation adjusted purchases has gone up more than 450% from 1990 levels.
This excludes military spending and is adjusted for the purchasing power of those dollars.
I don't know about you, but I don't feel like we are getting 450% more value out of the government services. The numbers are pretty clear that the government is collecting more and more inflation adjusted dollars from people's income than ever before.
I Suspect we would probably agree that the government is not being a responsible steward of this money that it is collecting.
My primary point was that I don't think that the belief that a decrease in government spending and Revenue is reflected in the numbers. Further, I think it is important to push back on the idea that the systemic issues we see can simply be solved by throwing more money into an increasingly inefficient system.
