A. The French stock market crashes horribly.

B. Thailand builds more public and private schools.

- Even if the resource exist, many of them couldn't afford it.

This is why building more public and private schools could increase the country's literacy rate. The private schools was made to take students from family who can afford to pay for the cost of education. The money will be distributed to the public schools which were targeted toward students who came from poor economic background.
