Not only that, but a lot of this thread seems to be, "Fault of the consumer" Which is all i heard after the collapse in 2008. Granted, there should be more fiscal responsibility than I see now, but banks make it pretty easy to get those large loans now that you couldn't get in past generations.
I can guarantee you, in the mid 70s if interest rates would have been floating where they are now, the ease of attaining credit were the same as it is now and the ability to get a 0% - 4% car loan, the, "Past generations didn't do this." would not be a valid argument at all.
Considering when I was a kid in the 70s, finance rates were closer to credit card rates across the board, is what made it more difficult for my parents to pull the trigger on a depreciating asset. I believe their loan, from 1968 on their home was around 15% or so.
So yes, were past generations less likely to be floating in debt as much as people are today, sure, but it's not like it was the great moral choice they were making. It just wasn't an option. There was a time you had to prove you were good for any amount of money you financed.
Hell even credit cards as they are now are more of a product of my generation than my parents. Sure, they had one, but it wasn't until around the time I started school that they started handing them out to any fool who wanted a free hat for signing up for one. Over all the process of getting credit of any kind was a lot more selective than it is now. It's why "Lay-away" was such a huge thing for generations past.
In the past, you were just forced to act as poor as you were. Hell, think about it, can't remember the comedian, but one of my favorite lines is, "If you are of average intelligence, half the population is dumber than you." Think about that for a minute. There are a lot of dumb people out there, if you allow them to be idiots, they certainly will not disappoint.
