For most of modern history, two-thirds of the income of most rich nations has gone to pay salaries and wages for people who work, while one-third has gone to pay dividends, capital gains, interest, rent, etc. to the people who own capital.

What a very starnge formulation!

Do nations have "income"?
Does the nation pay your salary?
Does the nation pay you a dividend? Capital gains? Does the nation pay you any rent?

In a perfect Socialist world, where the means of product are communally owned, then I suppose "the nation" might have a vast income, and might parcel that money out to the laboring classes.

But we're not there ... yet.

The author lies in the very first paragraph:

The fall of labor income, and the rise of capital income, has contributed to America's growing inequality.

Liberals by government action have made labor more expensive than it need be - FICA taxes cut income, but so do disability laws, regulations, agencies like the NLRB, etc.

Capital can flee for better pastures, but labor is sticky and doesn't move easily. Every additional attempt by government to fix nature, simply harms those targeted for help.
