I'd blame this more on sunspot lows than egos. Egos have always been with us,
but
we are seeing unprecedented poor solar conditions. Every cycle since 1958 has
been weaker
than the one before. Even solar max isn't what it used to be. It's no surprise
that people are
doing what they can to improve their station performance.
That said, given the cost of 2.5 KW+, you are talking about a handful of Big
Guns. The average
Little Pistol doesn't even have US legal limit and isn't likely to get there.

I've noticed the light pollution all right, but I'm not seeing global RF
pollution. It's mostly very
localized, in the ham's neighborhood, or even in his own house. That means it
can be fought,
case by case.
It's very RF quiet at my rural location. I'm not hearing a lot of
over-the-horizon noise. Hams in or
very close to cities have other problems, but those Big Guns that the previous
poster was talking
about are probably setting up their superstations well away from urban RF noise.
On 2 meters, I see a huge increase in noise when I point the beam at Boston,
which is about 180
miles away. It's quiet on pretty much every other bearing.

Yes, it irritates me to see an endless stream of comments in many forums along
the lines of
"don't get an amp, invest in better antennas," usually posted by hams with
legal limit amps. :-/
For most people, getting much past a half-wave dipole quickly gets very
expensive. In some
cases, the cost starts with the first step -- sell your house and move to where
you can put up good
antennas, without space restrictions, HOAs, close neighbors, etc. And that is
the point where most
will say, "Sorry, can't do that."
It's often more cost-effective to buy a 500 or 1 kw amp, rather than put up a
tower with full-sized
tribanders. And the amp will help on the low bands, where we spend more and
more time during
solar lows, but the tribander won't. (Rotatable beams for 40 meters and below
are the province of a
tiny population of elite hams.)
