Jonah, I got into that disability question a little in my socialism book. Interesting thing about the Swedes: Theyโ€™re among the healthiest people in the world, but their disability rate is more than three times that of some comparable countries, such as Belgium. I have searched the records in vain for evidence of some massive, 1.7-million-car pileup in Norrkรถping or a similar disaster that would explain these high rates. Possibly โ€” possibly? โ€” the relevant variable is economic incentives?
