Jacob 3:5-7 "how much better are they"

I find it interesting that Jacob calls his audience's attention to the righteousness of the Lamanites. It is very easy when we think we are "the chosen people" to look down on "those people in the great and spacious building" (hashtag).

"I don't drink or smoke like them."
"At the second coming I won't be burned like them because I've paid my fire insurance."
"I defend the family... unlike them [complete with head shaking]."

But Jacob teaches that they only do wrong because that's what their parents have taught them. Jacob makes it clear that family was important to the Lamanites. In fact, we can cross-reference these verses with 1 Nephi 17:20. In this verse Nephi's older brothers say:

"and we have wandered in the wilderness for these many years; and our women have toiled, being big with child; and they have borne children in the wilderness and suffered all things, save it were death; and it would have been better that they had died before they came out of Jerusalem than to have suffered these afflictions."

While his brothers may have been wrong, they were not oblivious to their wives' hardships. Perhaps the loving of spouse and children was taught among Lamanites from their first parents.

Jacob warns the Nephites that at the last day the Lamanites will be better off because the . (Yes I avoided the potentially racist phraseology.)

What am I to learn from this? Do I remember my own filthiness before the Lord or am I too busy condemning Babylon? Do I pay enough attention to my wife's hardships (we do have two almost three teenage boys and a 5-year old drama queen)? How much of what I believe is a product of the traditions of my fathers? (Note the plural... I'm not blaming you dad specifically but more generally the erroneous beliefs that have been passed down from generations.) I suppose if I believe Jacob I shouldn't spend too much time worrying about that last question.

"but ye shall remember your own filthiness, and remember that their filthiness came because of their fathers."

In the end, I need to worry about my own filthiness, not from whence it came, but I should remember the source for the filthiness of others.
