It is a very nihilistic philosophy. Unfortunately that philosophy is spreading, but it's also had an undercurrent there all along. There are a lot of people in the US that culturally do not have the same morals or system of ethics as the rest of the society, and they act out in ways which would appall the average person. This has been able to be mostly kept under wraps in the US because these subcultures, while shared across cities, on each local level are restricted to a small geographical area. With the rise of social media and the Internet, it has made the world a smaller place, allowing rapid communication between people with shared ideals and interests, and this is true for both positive interests and negative interests for society.

Car theft isn't even the half of it. Wait until you find out about the growth of card skimming in the inner city driven by social media. There are /many/ /many/ anti-social behaviors that are culturally rewarded within certain subcultures in the US. To even get to the point you have such a nihilistic world view, you have to have grown up in an environment without any serious positive role models, minimal to no hope for the future, and no realistic pathway in life to leave behind the circumstances you find yourself in. There are generations of people who have been bathed in this nihilism, and it's created a negative outcome for society on generational scale that's spreading.
