Because there are so many more US stations than foreign ones in any
particular country (except Japan 4th class). Working the USA is 1 DXCC
country.

That's an explanation, though perhaps not a valid one. We W's manage to
work all the DX there is to work despite the presence of strong QRM from
W QRM--both those who are ragchewing and those who are working DX.
Things aren't the same as in the old days when many DX stations were
rock bound or ran lesser quality equipment or had less than optimal
antenna systems. In fact much of the world runs the same Kenwood, Icom,
Yaesu and Ten-Tec equipment as the American stations. The garden
variety foreign stations sometimes QRM's the rare stuff. Many of the
garden variety foreigners are also in the chase for that same rare DX.
The time is long past for divided phone band segments. I believe that
the phone bands should be harmonized worldwide.

Here's a similar question: Why do 'phone stations need to be protected
from data signals but CW signals don't need that protection? IOW, why
not allow data modes in the 'phone bands?

I think the answer to that is that CW ops are typically using narrow
receiving filters while phone ops may be listening through 2.4 or 2.7
KHz filters. A little of that digital signal cacophony can wreak havoc
with a phone QSO.
