Step 3: Better learning and quality students

Step 4: ?

Step 5: Profit.

Trite, I know, but I feel this follows a similar argument to the one given for electric cars:

Right now, individual ecars don't help the environment because we still have inefficient sources of electricity. But, if everyone has an ecar, we would see huge increases in efficiency when we upgrade our power stations to green energy. 1 wind power station could affect 1000s of car drivers.

So if everyone has access to these books, an upgrade of the book could have a positive effect for millions of students..

Then: profit!!!
