First off, people to should be free to get up to their eyeballs in debt if they choose to do so. Greed and jealousy are emotions virtually impossible for humans to control. The financial acumen of the "depression era" generation is highly overrated and exaggerated. These folks paid for things in cash because they had no choice. Consumer credit did not exist. Even then, car loans are not a new "modern" phenomenon. GMAC was started in 1919. The depression era folks largely behaved the way they behaved due to the vast sums of money lost in the banking system. There was FDIC at the time. People from that generation were highly scarred. With that said, this generation did not shun the modern trappings of everyday life. They dived right in for fridges, cars, houses, tv's, etc just like any other generation.
Each generation is aghast at what the generation below spends their dollars on. I am old enough to remember when a serious technological upgrade to one's living conditions was getting a rotary TV antennae on the roof. Hell, my dad blew a gasket when he I told him I pay for Onstar.
