Don't know exactly what you mean here.
But most likely Romney wasn't the richest kid in his high school or junior high.
It was a rich kid's school.
Romney used his vast financial resources to kill off any competitors (10:1) before the real fight began.
Of course the REAL fight is the presidential campaign...and Romney's LDS money is paltry in that war.
But then Romney is not thinking of the country...he is thinking of himself and the LDS.
Of course, then Romney went to BYU and got his Mormon indoctrination...and there he established his "white horse" legacy.
