Many are not uneducated. Those that are uneducated are uneducated because American society has not bothered to find a way to educate them.
I do not think that any of this is at "record numbers". Crime has dropped quite a bit in the past 20 years.

If you study human society over the ages, you will see that your ideal concept of a proper family has been rather uncommon. Perhaps it is better for most, but human beings have been civilized for around 10,000 years, and there are many examples of successful individuals that did not grow up in the basic Ozzie and Harriet family structure. Reagan's father was the town drunk. Obama was raised mostly by his grandparents. Lincoln's mother died when he was nine, and his father was illiterate and lazy, and the family were squatters for a number of years. Mark Twain's father died when he was young.
