<i>LA unified school district alone has three times as many students as Singapore but only twice the budget</i><p>That's an interesting factual claim, which depends crucially on currency conversions between the United States dollar and the Singapore dollar. Do you have a link to a source for the factual statement, preferably one that "shows the work" (as a math teacher would say) by giving the school-age population numbers for each place and the all-sources primary education budgets for each place?
