I dunno...I'm rather naive and unsophisticated when it comes to financial matters, and I take it to "what it does to MY life".
DH's father was older, and was a kid during the Depression. From the info gleaned from FIL, the average joe's life wasn't necessarily changed THAT much. Farmers who had loans from the govt, yes. Wealthy people who had stocks etc, yes. But middle of the road folk, not hugely, according to the person we knew who was there (living in Oakland CA at the time). FIL's family would have been fine, had his father not drank and gambled the family's life savings away (and one is led to think that only happens nowadays!).
I tell ya, I've never been more glad for DH and my credit issues from our 20s, which taught us to be wary of loans they give to people who can't REALLY afford loans! Our families were hitting us HARD to buy a home with one of those junky loans, just b/c they are of the mindset that owning a house is everything...but we resisted just as hard back. And both sides of the family have now lost homes...and they had GOOD, proper loans...

They just made really bad choices with their finances after getting those good loans...
I see quite a lot of those store problems as being logical conclusions. The CompUSA near us had been shut, but not closed, for a couple years! It's only recently that a sign went up that it's gone. I don't know what they've been doing for those years of paying the rent on that place...
Starbucks just went nuts there for awhile. I believe I read that Schultz is coming back and his re-arrival goes along with their slowing down. Whew! Too dang many coffee places, too many Starbucks, they were becoming a parody of themselves. Thank goodness they did that re-training, b/c their lattes were getting naaaasty. But I thought they were just slowing down opening of stores, not closing ones they already have open...but I could be wrong.
Sharper Image was just a sad shadow of what it was in the 80s, in my opinion. You could get cooler technology at your local Target, and for cheaper, nowadays. And this, coming from a person who wanted nothing better than a huge shopping spree through their stores, back a couple decades ago...
But that's just one naive person's perspective of how it's impacting people.
