Dude. Nobody cares about percentages.
If I make $100,000 and I spend $1,000 of that on something, that's 1% of my income.
If someone else makes $200,000 and spends $1,000 on something, that's 0.5% of his income.
Same amount, lower percentage.
The average Marshall Islands child gets less than $800/year in educational funding. They're not spending "more" on education, they're spending the bare minimum on a budget of coconuts and tree bark.
6.1% of the U.S. annual budget eclipses the Marshall Islands GDP like a star swallowing a small asteroid. None of this matters as America pays for it.
Did you somehow think America and the Marshall Islands had the same GDP? That's the only way you make sense.
