It'll never happen. What's happening here is that email is
becoming over complicated and the operational expense is increasing
as a result - without (m)any results.

There is work being done on prevention. How about if MS could
bundle AV into the operating system (free)?

Great analogies, but we're talking about bits and nobody cares
about the plague anymore. If you shift the focus onto operational
expense, capital expense, revenue, etc..it might make more sense.
Trying to at least add some on-topic (about spam), the botnets
technically do NOT spam. They sell their zombies and the spammer
usually spams from a host located right here in the USA. The headers
are rewritten so that host is hidden, but it's there. Florida seems
to be the big place to hide-spam from lately.
The solution has to go up high in the network, near the
NSP's. At the exchanges. I have no idea what that solution is.
Best,
