A medical blogger points out how that has nothing to do with our healthcare system.
More importantly, though, is the statistical sleight of hand that proponents of this myth like to pull. That is, citing infant mortality numbers without proper context: in many countries (even "developed" ones), infants with severe or fatal conditions aren't even counted as live births (or are aborted when diagnosed), whereas we do everything we can to save such innocents. One may argue the efficacy of such an attitude, but we value life.
Case closed.
Another left-wing myth bites the dust.
