Is the writer so clueless as to ignore the past 200+ years of human history? All the evidence is there to see that using the adjective "some" is ignorance.
"Since the origins of modern capitalism around 1780, more than two-thirds of the worlds population has moved out of poverty. In China and India alone, more than 500 million have been raised out of poverty just in the last forty years. In almost every nation the average age of mortality has risen dramatically, causing populations to expand accordingly. Health in almost every dimension has been improved, and literacy has been carried to remote places it never reached before.Whatever the motives of individuals, the system has improved the plight of the poor as none ever has before. The contemporary left systematically refuses to face these undeniable facts."
-- Robert Novak, from the thread Economic Heresies of the Left (Novak on Caritas in Veritate)
