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

I think in the beginning of the CD they used 1 laser. You could do most anything to the disc because only one laser was doing the tracking. Now I think they use multi lasers and lots of error correction because of it. I remember they said these things would not skip, now all they do is skip if not taken care of. Similar to a vinyl record if you put you hands all over them.
I found this a while ago and is why I thought more than 1 laser pickup is use now.

Multi-beam CD-ROM Drives
A new technological development, the multi-beam CD-ROM drive uses 7 laser beams instead of one to to produce 36X performance from a 6X rotation speed. Six beams are used for reading data; the other one is used for error correction. A new development by Hi-Val in multi-beam CD-ROM drives, the first 40X drive, utilize 7 laser beams, reading simultaneously. (6 that read, and one for error correction, the same as above). The yield is true 40X performance and a transfer rate that can reach 6MB/second. The CD-ROM disc rotates as smoothly as a 6X drive.
I maybe mistaken again but don't most HiEnd CD players use Computer ROM transports and not cheap consumer CD drives. Like Meridian at one time used Toshiba transports not an off the shelf cd drive for better performance and access time.
