but how possible is it? Alas anecdotes are not enough for me, perhaps its time i do some of my own research. I have a striking impression that a person has a very limited capability to free themselves from their surroundings yet at the same time this makes apodictic that individuals posses significant power over other individuals. Thus i may have more influence over a friend than i do over myself. Which seems to be the sort of things that is nearly universally remonstrated.
Enough of that digression. I suppose it is just that that mantra discussed above is used as an a priori self-truth that forms the base for a vast amount of political and economical systems while it is entirely baseless itself. No matter the extent of my asking, prodding and searching no man nor paper has demonstrated that I am capable of triumphing over my setting.
Up until the last decade, income mobility was fairly high across a representative individual's lifetime (US-centric). For evidence I can link to here:
http://www.treas.gov/press/releases/hp673.htm
Here's the summary:
* Income mobility of individuals was considerable in the U.S. economy during the 1996 through 2005 period with roughly half of taxpayers who began in the bottom quintile moving up to a higher income group within 10 years.
* About 55 percent of taxpayers moved to a different income quintile within 10 years.
* Among those with the very highest incomes in 1996--the top 1/100 of one percent--only 25 percent remained in the group in 2005. Moreover, the median real income of these taxpayers declined over the study period.
* The degree of mobility among income groups is unchanged from the prior decade (1987 through 1996).
* Economic growth resulted in rising incomes for most taxpayers over the study period:
*
Median real incomes of all taxpayers increased by 24 percent after adjusting for inflation;
*
Real incomes of two-thirds of all taxpayers increased over this period; and
*
Median incomes of those initially in the lower income groups increased more than the median incomes of those initially in the high income groups.
There is a whole report there. There's evidence right now that mobility is declining currently, probably due to the recession and some bad policy choices by the Bush Admin. Note that that folks who put together such reports are career bureaucrats and mostly administration independent.
Anecdotal evidence, while inferior to statistical evidence, is evidence nonetheless. I know of many streets to suburbs success storie because I grew up in a pretty darn poor area. While many folks have not seen their financial standing improve upon that of their parents, those who had a demonstrably different drive (Hunger?) to do so did, regardless of race, sex, or family structure. It IS possible, but its not easy.
I'd happily point out other information sources, most the economics journals to which I am subscribed. I can really only cite sources, unless you have access to a subscription service (copyrights and all that)
