The Duggar father already had a great job before the first kid, and he decided to handle the whole family in 2002, if i'm right with the dates... they had a good financing then in time, but now as they are sponsored by the tv shows and companies to make their family live properly, they are driven by that and the fahter is working mid-time to keep $ for the future...

i also know that the oldest son, who got married this year, told the medias he would not have more than 4 kids... he is not worshiping his father's wills... he have a life of his own, and do not want the medias to follow him all the time.
