Computer Vouchers / Subsidies
Here's an interesting study on the effect of vouchers to purchase computers given to low income households. It turns out they're mostly used to play more video games - and actually kids grades dropped because they were spending more time playing video games. Use for homework was negligible. In fact the subsidies let the low income households play more games than the higher income households.
So if you ask me what I think about internet subsidies for low income households - nah - let's not go there. Not exactly the kind of social equity to be looked for.
