Что-то из Абрама Линкольна
Не пойму значение фразового глагола have through в следующем контексте:
I am a living witness that any one of your children may look to come here as my father's child has. It is in order that each of you may have through this free government which we have enjoyed, an open field and a fair chance for your industry, enterprise, and intelligence.
