> How can an article about "elite competition" not mention anything about how, during a few decades in the 20th Century, labor's share of profits increased, and since 1980 has flatlined, with all rewards accruing to capital?

As far as I can tell, the share accruing to land increased. The share accruing to capital stayed roughly flat.

In any case, the labour share didn't drop all that much. A few percentage points.

The bigger deal is perhaps the change in distribution of that labour share amongst workers.
