Maybe you would have more luck if you cited better sources. I clicked on your link and just got a page of dozens of Excel files. Which one are you referring to?
On P7, it says median income in 2017 was $31,786. In 1974 (as far back as the data goes), median income in 2017 dollars was $23,984.
That's only a 32.5% increase, not 100% like you claim.
Per capita income doesn’t tell you about what went to generic “workers”. Nearly all of the income increase has gone to the top, and a higher percentage of adults are working now (most women have formal work now).

Do you have reference for this claim? That really wouldn’t make any sense. The appropriate technical term for median income is “median income”. “Per capita” always implies total divided by population, i.e. the mean.
> Per capita income is the mean income computed for every man, woman, and child in a particular group including those living in group quarters. It is derived by dividing the aggregate income of a particular group by the total population in that group.
