How could society be structured to guarantee higher wages to unskilled workers?
How could society be structured to guarantee higher wages to unskilled workers?
What you just described is a family of 4 with a total income of $30k+.
Per capita GDP of $45k means that GDP per 4 people is $180k. That $45k number is per person, not per worker.
So either the claim is that $30k is not that bad compared to $180k (unclear, a priori) or ... something?

I agree that household income is a more interesting thing to compare to for this case, though, but even more interesting would be comparing to similar households. Otherwise you're comparing the income of our hypothetical family of 4 to the incomes of 1-person households, incomes of households containing just a student, incomes of households containing one or two retirees, and so forth.
Luckily for us, such information is out there; http://www.census.gov/hhes/www/income/data/statistics/4perso... lists the median family-of-four income in the US at $67,000 or so in 2005 (though by state the median ranges from about $50k to about $90k, which shows the problem with talking about aggregate "United States" numbers). http://www.census.gov/hhes/www/income/data/Fam_Inc_SizeofFam... has similar numbers for a few years later... http://www.census.gov/hhes/www/income/data/historical/househ... has quite a bit higher numbers than that for 2011 ($75k median nationally), which is a bit surprising to me, actually.
None of which answers the question of how reasonable an income of $30k is for a family of 4, of course.
