Paging through the Brookings document, it tracks pretty closely with what I have seen before. I dont see anything that contradicts what I have said (mobility is higher in the US than elsewhere). 1) Do you have a comparison with European countries that makes you think the US is worse? 2) What do you think US mobility numbers should look like? Pure randomness is not desirable either.
