Volume. Economies of scale. Etc.Ethernet is cheap because it's everywhere, and built into almost everything. (however, the likes of Cisco and Juniper still charge insane amounts for line cards, be they ethernet, T1, or OC48.) Given the choice of buying a $4k DS3 card or just plugging into an existing, builtin ethernet port, which do you think most people will choose? And it doesn't take a multi-thousand dollar Router(tm) to deal with ethernet -- a 200$ "trash" PC can handle routing (and NAT) for a great deal of traffic. (in many cases, *better* than the high priced kit.)
Case in point, our voice/data line from TW enters the building as fiber (along with about 4000 other circuits), crawls up the inside of the building as HDSL (single pair) to a box in my "closet" where 8 POTS line and an ethernet are handed to me. The ethernet runs to a switch and then to the firewall. If it wasn't handed to me as ethernet, I'd need a router to turn it into ethernet. (On the other wall... $8k worth of gear to turn a DS3 into ethernet. Yes, the Optera Metro shelf at the other end of that DS3 could just as easily be an ethernet port -- but that would require TW and VZB to play nice with each other; it was enough of a pain to get the DS3 to work. But that's miles off topic.)
