Meanwhile average mobility in the US continues to be worse than mobility in other countries.

What's the best study you can find that demonstrates this? I haven't seen any that don't appear to succumb to the flaws I mentioned elsewhere in this thread, such as measuring relative mobility instead of absolute mobility.

We should probably define terms first.

Which definitions of absolute and relative are you using? (There are a few, and they're not identical.)

[twoodfin]

I would define absolute income mobility in terms of some globally comparable good. Dollars, PPP adjusted or not, for example.

Relative mobility to me means mobility within some particular income distribution: Moving from, say, an average household income in the first quintile to an average household income in the fifth quintile.

I prefer absolute mobility as a measure of economic mobility for the same reason that any rational actor would prefer to win a lottery for the difference between the income of an average bottom 20% household and an average top 20% household in the U.S.[1] vs. Sweden[2]. According to OECD, that's $75K vs. $37K.
