yup, that part of the definition of capitalism.


Probably more than 15 cents but not very expensive in any case. But what's
your point? How much does it cost to "make" another e-book? Should we
therefore give them away for free?


Of course not. I don’t think that’s ever been suggested. The issue is, who pays.

Every one knows who I think should pay.

Instead of a tone control a reduced graphic equalizer with three octave

For me at least, simply increasing the volume does increase
intelligibility.


bc thinks those audio people are capitalist pigs, as Ludwik suggested.

Hearing aids are very expensive, typically from $3000 to $6000 a
pair.

But some people might wearing them, for many year.

I describe this alternative at my university website:
