Analogy for educational exemption for Internet access

Think about those newspaper boxes on the sidewalk. They come in two flavours - ones where you have to pay before you can take a paper and ones where you can take a paper without paying.

Now imagine the proposal that everyone should have to pay a "sidewalk tax" which goes to the book publishers to compensate the people who print non-free newspapers and put them in the "please take one for free" newspaper boxes.

Then imagine the proposal that teachers should be exempt from this new tax.

Even people with little interest in Copyright and the Internet tend to respond "but if they're stupid enough to not use the "pay first" boxes, they don't deserve to be paid for the papers".

I have visions of setting up one of these boxes outside the House of Commons...
