…Well. Just the one, really.
Megan McArdle pretty much nails it here:
The technocratic idea is that you put a bunch of smart, competent people in government — folks who really want the thing to work — and they’ll make it happen. But “smart, competent people” are not a generic quantity; they’re incredibly domain-specific. Most academics couldn’t run a lemonade stand. Most successful entrepreneurs wouldn’t be able to muster the monomaniacal devotion needed to get a Ph.D. Neither group produces many folks who can consistently generate readable, engaging writing on a deadline. And none of us would be able to win a campaign for Congress.
Yet in my experience, the majority of people in these domains think that they could do everyone else’s job better, if they weren’t so busy with whatever it is they’re doing so well.
