It is very common for pencils to have a rubber at the end here in the UK - you can buy pencils with and without in any stationary section.

Borrowdale,
England, UK.Also, saw some documentary few days ago about Faber-Castel and found that the only abroad (?) factory is located in Brazil, something that I think that justifies theier almost monopoly around here.

But the fundamental point of "I, Pencil" (and the intellectual tradition it's part of) is that you can't plan the economy at large. It's becoming increasingly clear that you probably can't even plan a single company once it's over a certain size (the essay seems to touch on that point, but doesn't really follow through). It's not that private companies or markets are better at planning, it's that the sheer inherent complexity of an economy is so large that any kind of effective planning is impossible.
WalMart has an annual income of $482 billion.[1]
That's more than the annual GDP of Poland, as measured by the World Bank, the 25th largest economy in the world, and of Belgium, the Philippines, Thailand, Norway, Iran, Austria, the United Arab Emirates, Egypt, South Africa, Hong Kong, Malaysia, ... and 153 other countries (163 total) in the world.[2]
Unfortunately, few problems in the world are like that, and that's why large companies (and governments) fail to address them effectively.
The pens I use now take a few seconds to dry, and so would probably be a problem for leftys. For me, they work great, and I only occasionally smudge something.
Here[1] is a scan from today. This page (and the entire notebook it comes from) has been fully erased about 10 times. (I scan in all of the pages, and then wipe 'em clean once I've filled the notebook).
Wiping can be a bit more time consuming than with a normal whiteboard. The manufacturers claim all sorts of things will work to wipe an entire page, but I've found that for best results you need to use cotton balls + pure acetone.
1 - some people even collect pencils, and most of the collection is from merchandise pencils, not commercial ones (source: one friend)
2 - pens are usually borrowed and never returned, even without knowledge of the owner. Pencils, on the other hand, are hardly borrowed, and are almost everytime returned to the owner (source: 2 unrelated friends)
