I'll confirm this. I'm much older than the "younger" generation and I have virtually nothing compared to my parents and theirs. I can get everything I own in a 45l bag and a large box. They can't get all their crap in a 4 bedroom house with a double garage.

Also as a side issue, yes you're right; absolutely nothing out there is worth much any more. The Internet and particularly eBay has laid waste to the value of things by making everthing ubiquitous.

Another effect of the internet is that it is now trivial to find out the second-hand value of something.

I suspect that, say, garage sale prices are much more likely to approach eBay prices than was the case in the '90s. Though the local-ness of yard sales probably means there are still arbitrage opportunities.
