Middle

You see? Although people with much time and little money are more likely to be treated by the government general clinic, the situation is very different in the case of the Student Health program. Yes, it does occupy precious time of the parents, but the grassroots are not the only likely group to participate and enjoy the benefit.

The reason is simple. To receive the benefit of this program, parents (like me) need to take a day off in order to bring their children for the check up. For obvious reasons, unemployed people have no problem. On the other hand, parents from the upper class (who either run their own business or have a well-paid administrative job) will also find it easy to join. Yes, their time is precious and hourly paid is high, but they would have little difficulty to leave their duty for a short while.

The problem lies in the middle class with working parents. Their hourly paid is not as high (or, in economist's term, their time is less precious), but they would have more difficulty to take leave from their job.

PS. The phenomenon that I outlined is the classical problem of using time as the payment, because the cost of time is neither flat (equal to everyone) or linear (proportional to the hourly paid), but has an inverted U-shape relation with the income. It is not the classical Kuznets curve, but it looks very much the same.
