Question

Why are educated unemployed person are going to nearby cities

Answer 1

As you said they are educated, now the are enough educated that they are not ready to work in village as labourer or any other such low salary work. They are not capable of doing such works because they are not physical labourers, they work mentally & such jobs are only available in cities that's why they are moving to nearby cities.
Hope it helps.

Answer 2

They are going to nearby cities in search of well paid jobs tht can feed their family... they would prefer to work in the beeteer jobs as they are educated..
