Why do NOS Tubes sound better than new tubes?

Is manufacturing really that backwards in todays techno world? What is the real reason that todays tubes cannot equal the tubes of yesteryear?

There are good ones and bad ones. I prefer the Winged C 6550 to the GE 6550 for many reasons. First, the WC sound better, less shrill treble, better bass, and more reliable. I do like the Amperex BB 12AX7's. But I hear from friends, they have replaced theirs with the GL 12AX7's and like them as well or better. I think new tubes can be very good and just be open minded before spending 300.00 for a rare NOS that may not be any better. Tpreaves is asbsolutely right.
