Did Ben Carson speak accurately?

Did Ben Carson speak accurately? " There were other immigrants who came here in the bottom of slave ships, worked even longer, even harder for less. But they, too, had a dream that one day their sons, daughters, grandsons, granddaughters, great-grandsons, great-granddaughters might pursue prosperity and happiness in this land." ​
​Dr. Carson is one of the world's greatest surgeons.  And speaking logically and accurately is common among physicians.  For instance.  The medical classification for a miscarriage is "inevitable abortion". Cold sores are classified as "Herpes simplex One". The problem is the poorly educated public.  People are far too connotative in their perceptions.  We are taught to worship our own feelings.  And we even enslave others' speech to conform to our feelings.
