Let me just bring up one historical parallel to put complaints like this ("if we ease up on controlling and punishing some particular group, this will greatly decrease society's productivity") in context. Such rhetoric was very common in the 18th and early 19th century, and its object was the proletariat and poverty. Here's a paper and an article about old-time Malthusian/anti-worker beliefs held by elites.

"The possession of a cow or two, with a hog, and a few geese, naturally exalts the peasant. . . . In sauntering after his cattle, he acquires a habit of indolence. Quarter, half, and occasionally whole days, are imperceptibly lost. Day labour becomes disgusting; the aversion in- creases by indulgence. And at length the sale of a half-fed calf, or hog, furnishes the means of adding intemperance to idleness."

"Poverty is that state and condition in society where the individual has no surplus labour in store, or, in other words, no property or means of subsistence but what is derived from the constant exercise of industry in the various occupations of life. Poverty is therefore a most necessary and indispensable ingredient in society, without which nations and communities could not exist in a state of civilization. It is the lot of man. It is the source of wealth, since without poverty, there could be no labour; there could be no riches, no refinement, no comfort, and no benefit to those who may be possessed of wealth."

In my opinion, this justification for class warfare from the top is analogous to such justifications for anti-feminism as seen today.

Tl;dr, from the outside view, the author is not in a good reference class.
