Do you have any economic data that supports the claim that 'growth', as you use it above, has a high correlation to the median wage (not mean wage) of U.S. citizens, or to their overall financial security, or to their ability to buy a home, send their children to college, afford health care, retire comfortably, and so on? Why should we care about growth if it ...[text shortened]... edia.org/wiki/File:Historical_median_personal_income_by_education_attainment_in_the_US.png
I am not sure the US census data themselves support the oft-made claim of income stagnation for most US citizens from about the 1970s onwards.
Consult this document on consumer income.

Here, see the data on real median household income for all races (Figure 1, Page 6)
Consult this document on household size.
http://www.census.gov/statab/hist/HS-12.pdf
Here, see the data on average household size (Pages 1 and 2)
Now, consider the period 1967 to 2002.
In 1967, real median household income was 40,000 and average household size was 3.26. That's 12,269 per person in the household.
In 2002, real median household income was 50,000 and average household size was 2.58. That's 19.379 per person in the household.
This represents a 58% increase on 1967 incomes levels per person in a household.
This is not quite stagnation, supposing the funds distributed among its members count as income to those persons.
From the data, however, one might infer only a smaller increase in real *wages*, assuming that each household has a less temporally variable number primary breadwinners.
But still the primary trend in inferred real wages would be definitely up, by around 25% overall assuming a single breadwinner.
Furthermore, as the same real money now buys better products than the same real money in the past, even stagnant real incomes and real wages would not mean stagnant real wealth. So real income and wages would underestimate increase in real wealth.
But: was this rise in real household income mostly driven by increases maade among the already rich households?
That the real median household income for Blacks, Whites, Hispanics, and Asians, all who have different average income levels, grew similarly, suggests not.
This equivalent rise across all racial groups is hardly solely an artifact of differential changes in their household size.
Moreover, it is noteworthy that the incomes of generally poorer Blacks, intermediate Whites, and richer Asians, not only all grew, but also all grew *in tandem*.
That is, poorer Black households started to see their incomes rise at the same time as richer Asian and White households did. Hence, there is no evidence here that the latter rose at the expense of the former.
However, according to this data, there really *does* seem to have been income stagnation from about 2000 onwards.
Over this period, median family income, including in all groups, remains about the same, as does overall average household size.
This is indeed odd, given that it was supposedly a period of "growth".
On the other hand, data from the Centre of Budget Policy Priorities suggests that incomes *have* increased in all income groups since 2002, albeit to a greater degree the richer the original income group.

But the oddity is that, since *all* income groups increased their income *somewhat* according to the CBPP data, the increase does not also register at least *partially* on the median household income for all races according to the census data.
So perhaps one shouldn't wholly trust on a single official dataset.
Still, there are again positive correlations over time between income across all income groups. Assuming limited or no income mobility, the rich [in terms of income] get richer faster than the poor get richer, but the poor *do* get richer as the rich get richer.
