Helping to foot the bill on education is everybody's responsibility.

The costs to society would be much higher, and you'd be paying much more, if the majority of the society were illiterate.

I didn't have my house burn down last year, but I'm not going to stop helping to pay for the fire station because if the neighborhood burned down, the cost to me would be higher than if I just help pay my fair share.

Try looking a little further than just your self-interest and understand you've got a responsibility to society at large.

You want to think you go it alone?

You're 'outside' the system, independent and therefore shouldn't contribute?

  Maroon yourself on an island. You benefit from an educated population, don't kid yourself.
