Do you think the people of south africa learned alot from Michele Obama and her kids or do they more guidance?

as you know michelle obama and her kids went to south africa to read them stories from a kids book, teach em about the world and pull carrots out of the ground. she also did a speech or two there, to make sure its an Official trip and not a vacation. do you think she has taught them enough about the world and are better people for it or she will have to go back for another visit?
