Perspective
There must be a million possible objections to this, but the prima facie case is awfully compelling: we're not getting our money's worth when it comes to spending on education.
There's a reasonable argument to be made for emphasizing education and even for funding it publicly. But at what point to we start to ask questions such as Have we reached the point of diminishing returns? Can we plausibly argue that the return on the last dollar of education spending is positive?
As I have pointed out before, while this kind of cost/benefit calculation is done routinely in the real world, where non-performance is punished by bankruptcy or unemployment, it seems never to happen in public education. We are asked to take on faith not only that some spending on education produces worthwhile positive externalities, but that every dollar spent on education produces the same return.

Picking your poison
I suspect that differences of opinion on questions such as, Do we spend enough on education? Should we have national standards? What is the role of government in education? Are vouchers and charter schools a good idea? are really about the trade-off between equity and excellence.
The fundamental disagreement can be seen this way. The graph below shows two hypothetical distributions of educational "goodness." Both options are represented by Gaussian curves, but they could be any shape. Option 1, the "Unfair but excellent" distribution, has a higher average, but more extremes at the high and low ends. Option 2, "Fair but mediocre," has a lower average but a tighter range.
If you could wave your magic wand and select either distribution for education in America, which would you choose?
There's no wrong answer, here. There's an argument to be made for either being better. The one you'll choose depends on whether you think equity or excellence is more important. I suspect that much of the educational establishment (can I use that term?) places more weight on equity -- ensuring that no child is left behind. Somebody like Charles Murray, who believes educating the future elite is critical, would disagree.
So? What would you do?

Oh, for...
PETA has taken a stand against one of the most popular tourist attractions in Seattle - the fish market at the Pike Place Market that tosses salmon.I'd respect PETA more if they were protesting the fact that the Pike Place fish market murders innocent fish and sells them as food to omnivores who could just as easily be eating tofu or hummus or something else that doesn't have a face. Dudes! The fish are dead! They're in fishy heaven enjoying the benefits of eternal bliss and all the worms you can eat without hooks. Or they're waiting in line to be re-incarnated as, I don't know, otters or something. At any rate, they're not in any pain. I don't think -- I'm not really an expert on fish theology.
It's gotten to the point where it would be impossible to satire PETA. (Can satire be used as a verb? Can fish be used as a projectile?) Anything you made up about them would be less outrageous and silly than whatever it is they were actually doing at that moment. Here's what I mean.
PETA has begun a campaign to improve the public's perception of man-eating tigers. The organization has developed a web-site, targeted to children, suggesting that man-eating tigers be referred to as "jungle goldfish."
In an effort to make life a little easier for sheep, PETA has sent a copy of "Babe" on VHS to New Zealand. Said a PETA spokessheep, "Baah, we just want the dogs to stop being so gosh darn mean all the time." It is not certain whether the island nation, located to the south of Australia, has made the switch to DVD...
PETA is trying to get everybody to stop eating tortilla chips because one of the group's members was in Tijuana for a bachelorette party and she saw a diorama with actual stuffed frogs playing in a mariachi band...
Update: Seriously.

Pity the SAT people
A nice summary of the trials and tribulations of the SAT, from the Weekly Standard.
Those poor SAT guys, they’re doing their darndest to square this circle. You want a test that will highlight the diamonds in the rough? No problem, we’ll give you an aptitude test. Ah, you want a test that shows that all races and classes and sexes and “others” are equal? Okay, how about if we give you a string of random numbers (or, better, chicken entrails!) and you can use that for admissions. You want both? Hm... Well, we, uh... We may have to get back to you on that. Meanwhile, how about if we change the "A" in "SAT" to stand for "African American" as a sign of goodwill?
(I exaggerate slightly.)
Listen, it's time to consider -- just consider -- the possibility that we're not all alike. Some of these variations, like skin color and whether your hair is straight, are not terribly relevant. Others, like footspeed and cognitive ability, matter more depending on the situation. We can't go on pretending that any test that suggested differences among races is necessarily biased. Psychologists and test-writers are just like the rest of us. If they could devise a test that both a) tested cognitive ability in meaningful way and b) showed no differenct among races, don't you think they'd have done it by now? I mean, the profit potential for the creator of a test that separated the smartest from the less smart and did so in racially proportional way is practically infinite.
