Over the course of my life, I have made different amounts of money.   As a low-level non-profit employee, I was, well, starving.   Two bagels with butter was a once-a-week dinner splurge.   Now?   As a capitalist?   Not so much.

In the eyes of economists, I have been “economically mobile”.

Economic mobility, it turns out, is tricky to measure.   Do you look at income?  Or wealth?    Whatever you look at, how do you associate it with a person, and their partner/kids over time?    When measuring income, do you count governmental transfers?   Or not?   Is self-reported income or wealth data, drawn from a statistically valid population, a better measure than more accurate tax data, which by its very nature excludes non-filers?  I dunno.  Smarter people than I have made a profession of looking at this information.   And they have come one very suprising conclusions.

Income mobility in the US is relatively unchanged over long periods of time.   It is just as easy, or hard, to change your income now as it was back in the day.


The American Dream is still alive and well.
