> Why is $85B automatically bad?

I didn't say automatically, I referred to "my words above" - that kind of money, and the profits on top of it, can only come from monopoly pricing and it's a strong sign that the business in question is operating in near monopoly conditions.

In most of the world, railroads (and other roads) are government owned because it's hard to make that kind of business competitive plus there are natsec issues to address. The privatization trend is recent.
