Wasn't it he who first pointed out that memetics was a meme too?

Counterexample: Kilroy was here. Was started by some soldiers, and
was so efficient that it spread across most of the western culture.

There are plenty of memes not invented by the rich and powerful which
spread well, but the rich and powerful can of course support memes
more effectively (broadcasting is very useful).

No. Let's make a BOTE mathematical model for memetic spread in a very
large population (assumed infinite in this case). Let x(t) be the
number of people infected with the meme at time t. They infect other
people at a constant rate k. There is also some agency which spreads
the meme deliberately, infecting new hosts at a rate l. Assume that
infections last for life. Then we get the differential equation:

x'(t)= kx(t)+l

This has the solution x(t)=c exp(kt) + (l/k). Note that the first
term, corresponding to the exponential spread of the meme
person-to-person will overrun the second corresponding to outside
insertion quite quickly.
