Are Things Looking Up in Africa?

There has been some news lately about economic growth in sub-Saharan Africa. And that's good. But these things have to be kept in perspective:

The port of Dar Es Salaam deserves a post of its own, but here's the short version: it used to be horribly congested, totally dysfunctional. So the port authority made an aggressive effort to fix the problem. And now it just somewhat sucks. It's still a bad, congested port where containers may take weeks to process, leading to annoying storage fees and possibly the loss of perishables. But it's no longer a godawful port where everything always takes weeks or months to process, and may disappear altogether. It's gone from horrible to just bad. That's real progress.
