I can only guess based on experience of talking to many stations around
the world, but perhaps 15-20% of hams in the US run 800 watts (or more)
for output. Then there is the QRP crowd, which might be a percent or
two. We have a number of QRPers in this area and I think that's well
more than average, but it's still less than 10% and more than half of
those have the capability of running 100 watts or more. It's just one
more facet of ham radio.
Although we refer to the legal limit as being QRO, in a number of
countries outside the US some of the hams really run QRO compared to our
legal limit.

Unless both stations are running the same power there will always be the
disparity between hearing and being heard. Even then there are no
guarantees. Sometimes when any particular band is really open it becomes
difficult to tell how is running power and who is only running 100 or
200 watts.
The same is true for a noisy band. 160, 75, and 40 are particularly
prone to QRN and the warmer the weather the worse it gets. If 75 is
open in the evening, thunderstorms from Georgia to Florida, to Texas can
be S-9 or louder up here in the central part of Michigan. That's when
you hope for some one out there to call you that is running power. OTOH
if you call CQ running power when the band is noisy in your area you are
likely to miss quite a few answers from areas with less noise. In the
massive pileups power may be a considerable help for the one running it,
but timing and technique will trump power quite often unless the station
is running REAL POWER. OTOH some one in the pile up running power, but
with poor timing and technique is a hindrance to every one.
Still if it gets the station with poor timing and technique out of the
pileup quicker then the rest of us benefit.
Remember that power like many things is a double edge sword
