I think that this writer has touched on the most important factor that is causing the current dulling of resistance to the rule of the plutocrats. It is the internalization of that part of ruling class ideology which justifies the existence of poverty: poor people deserve their fate because they are lazy, incompetent, or affected by some character flaw. This indoctrination comes in daily doses and results in a deep feeling of shame for those who, for whatever reason, find themselves needing social assistance, or just not being able to afford all those things that are advertised on TV that everyone else of worth seems to have. This phenomenon is a powerful influence on our lives, but yet it remains mostly hidden because it is so heavily laden with feelings of shame.
Thinkers like Malcolm X pointed out that it wasn't enough to change the political conditions of a people; subjugated people also had to stop viewing themselves through the lens of dominant culture, had to shake stereotyped, degrading visions of themselves that they had too often internalized.This brings to mind a recent incident I had with my visiting sister who after the visit wanted to assist me with the purchase of a newer car. I drive a 1993 Saturn which has served me so well--it's the best car I've ever had, and it has saved me so much money. I was surprised by this offer because the car runs as perfect, and looks nearly as good, as the day I bought it new. It finally dawned on me that my very conventional sister was ashamed for me to be driving such an old car.
Unfortunately this liberal author does not see this indoctrination as an integral part of ruling class culture that serves to justify the system of capitalism while keeping working people in their subservient places.
