What is that statement based on?  I have not seen any outcry for more symmetric speeds.  Asymmetry in our networks

symmetric circuits.  It would be nice but the users generally download more than they upload.  That is the fact.

The demand may not be symmetrical, but where demand exists, it is often for symmetrical speeds.

Side note:  Did I not read that asymmetric paths tend to exacerbate Buffer Bloat?

"the users generally download more than they upload.” may well be true, but is refers to bytes moved, not bytes per 
second.

And, again, what about Buffer Bloat, especially due to considerably slower uplinks?
