Subject: Re: OT mostly: forevers
Besides Berkshire, mostly a few oligopolistic contenders:

Visa and Mastercard
Moody's and S&P Global
Canadian Pacific Kansas City
Copart

Nice thoughtful list, thanks. I like the Visa idea. Moody's, railway, I see the unkillability case. (I used to work for CN, so CP is not entirely unknown)

But I know precisely nothing about Copart. What's the elevator pitch in this context?
