I think these are good reasons why our fiscal picture is not hopeless, but not good arguments agains improving our efficiency:
1. Thank you for linking that graph, it seems to show that our spending is 25% higher than it was in the 1970s as a % of GDP (23 vs 18). But our level of _debt_ is approx 375% higher (as a % of GDP) than it was in the 70s (120% now vs 32% then). That doesn't sound like we are sustaining it well, and tht interest is compounding as we borrow to pay it.
2. The underlying assumption that makes this argument compelling is that every dollar being spent on these noble categories is being done efficiently. What if fixing healthcare costs cut them in half for the same effect? What if there is fraud to cut in the programs for the elderly? We should tighten these and prepare to pay more as we age.
3. Strongly agree and hope to see some action. It seems that fixing the incentives and inefficiencies of the healthcare system is the core mission of RFK Jr., despite all the vaccine FUD.
4. Strongly agree. I wonder if a VAT would be effective for this.
