They are out there. I buy the thick cloth T-shirts from Uniqlo (the ones that cost ~2000 yen - $15? - a piece), and I've got some that still are fine for work ten years after I got them.
One thing that has changed is that many people now tumble-dry their clothes rather than hang to dry. And that rapidly wears out the cloth. Changing washing habits may explain part of the difference as well.
