But even the chart disaggregating scores by race shows that within each group test scores barely went up since 1990. Meanwhile, inflation adjusted per student spending has increased 30% since then.

Costs are out of control due to nuclear regulation.

That's a political and economic question, not a scientific one. Science can provide input information, but the decision involves weighing all sorts of facts and considerations outside the scope of science.

It seems like a rule designed by journal editors to protect their turf, or PhD committees to make it easier to count original works towards degree requirements. What could possibly be the justification?

Why wouldn’t you include state spending? That’s the level of government primarily responsible for infrastructure and education.

by rayiner 4mo ago
You have to include state and local spending too. We’re at 40% of GDP which works out to almost $13 trillion: https://fred.stlouisfed.org/graph/?g=1CFpQ . Subtract $1 trillion in defense, and we’re spending about $1 tri

So why has per-capita student spending doubled since 1990 (adjusted for inflation) without any increase in test scores? Why haven’t we been spending the money wisely? Student to teacher ratios have continuously decreased and are about half

by rayiner 4mo ago
Diminishing returns. Per-student education spending has been going up since 1990 except a dip during the 2008 recession. Adjusting for inflations it’s now double what it was 30 years ago.

Thank you for the sources. The NYT article citing the Maggie Haberman book is reporting that Trump was warned protecting the strait would be difficult. I will have to read her book on this, because it’s unclear who was part of this “inner c

by rayiner 4mo ago
I don’t think we can assume that. Maybe Trump ignored warnings (though if that happened I would have expected it to be leaked). But there’s also a possibility the Navy fucked up. And that’s important to consider, because that’s something th

I don’t know. My prior is that this admin was never willing to put boots on the ground. And for purely self-serving reasons, they wouldn’t have risked a scenario where Iran blocked oil traffic through the strait, causing gas prices to go up

by rayiner 4mo ago
Do you think the military gave a realistic assessment of what time and resources it would take to control the strait? Was this pitched as an operation that would take a huge political commitment of troops and drag on for years?

Nobody is talking about how big of a failure this has been on the part of the U.S. Navy. Controlling and securing shipping routes has been a fundamental function of a navy since Roman times. The U.S. Navy was unable to achieve that objectiv

That’s just federal spending. $17,000 sounds too high to just be federal taxes, it looks like federal + state/local. Accounting for that, military spending is closer to 10%.

by rayiner 4mo ago
Total government spending in 2024 (at all levels) was about $9.5 trillion. So the military spending of about $950 billion was 10% of that, or $1,700. Interest on federal debt was also about 10%. It’s worth also looking at what other countri
