Two thousand five hundred years ago, the problem of population did not exist. There was poverty and there was also unemployment, to some extent, but the population was not large. The system was village-oriented. People managed their living within the village; they produced everything there. All basic needs were met within the village itself. At that time, not many diseases affected the people. Common diseases were treated with medicinal herbs found in the forests. In the present age, the population has increased excessively. There are no resources to meet the needs. Villages are being deserted and big cities are coming up. The population of each of the three metropolises exceeds ten million. But, on the other hand, everything is dependent on the villages and their produce. In a situation like this, the problem of unemployment has increased. There is a lot of work, but the professional qualification is not available universally. That is why the problem of unemployment has risen so alarmingly.
