Why are CD's decling in quality?


When CD came out in the 80's , they were marketed as 'indestructible'. They were built in such a way that they were almost impervious to any scratches and other damage.
As time went on, they declined in quality to the point that you could buy a cd and find it skipped on the first playing. Now many CD's I buy in the 21st Century seem to be incredibly vulnerable to damage. This is very frustrating.
.Does anyone have any suggestions or thoughts on this topic?
Or knowledge of why this has come about

They are quite durable but not indestructible. The
designers did a very good job with the technology of the
time (which has improved vastly since) for CDs to still be
where they are 30 years later.

How many gadgets designed 30 years ago are still relevant
and so widepsread?
I have not found the quality of the modern CD disk to be inferior over time. That said, buying prerecorded CDRs is a different story; it's buyer beware.
But, I think others will share my practice of treating a CD as I treat my vinyl, with kid gloves.
I'll join the chorus of others here. I have hundreds of CDs of all vintages and have had zero problems with them. In fact Red Book sounds wonderful in my system and I'm glad they're still widely available.

ok thank you for the replies. I guess the problem is cdp related, well just bought the ARC mk3cdII so Ill soon know I guess, it will replace my pioneer transport which is old and broke down twice though I liked it a lot,
Elizabeth, great suggestion, I do care for the cds and did find try to keep them clean , perhaps a soft brush will help
Also listen to classical and have the same problem.
As to Redbook cds How do you know if a cd is redbook or not?
