Before 1979 education wasn't a federal issue. Before that kids were arguably smarter than they've ever been. So why is federal education a good idea?

Actually there's evidence that the generation of kids immediately before 1979 were the least smart, and it's been getting better since 1980. Source: Who is the Real 'Dumbest Generation'? - washingtonpost.com
And a pertinent excerpt:
"...the long-term results of the National Assessment of Educational Progress (NAEP), which is housed within the U.S. Department of Education. Considered the gold standard in assessing K-12 students, the NAEP has been in continuous operation for decades. Here's the bottom line: On both the reading and the math tests, and at all three tested ages (9, 13 and 17), the lowest-ever scores in the history of the NAEP were recorded by children born between 1961 and 1965.
The same pattern shows up in SAT scores. The SAT reached its all-time high in 1963, when it tested the 1946 birth cohort (including such notables as Gilda Radner and Oliver Stone). Then it fell steeply for 17 straight years, hitting its all-time low in 1980, when it tested the 1963 cohort (Mike Myers, Quentin Tarantino). Ever since, the SAT has been gradually if haltingly on the rise, paralleling improvements in the NAEP. In 2005, teens born in 1988 scored better on the combined SAT than any teens born since 1956 -- and better on the math SAT than any teens born since 1951."
