Most studies show that the members of rural communities who are most likely to migrate to urban centers are those who have been to school. The studies seem to show a consistent positive correlation between an individual's level of education his propensity to migrate. REASONS (1) The income gap between what the 'educated' ones can earn in urban areas compared with their rural opportunity cost is larger than it is for the illiterate ones.(2) The educated ones are more likely to obtain a lucrative modern sector job. But because jobs are scarce,a large proportion of those who migrate often remain unemployed.
It would really help if you actually included facts and references instead of assumptions. Especially on point 2 you seem to contradict yourself. In many rural settings there are few jobs for the younger generations, especially if there is a lot of them, so they have little choice - often the jobs will be more manual & labor intensive which might not suit everyone, plus the wages get suppressed. Someone that is willing to relocate opens up a lot more opportunities, especially when moving to an urban environment with qualifications. You will always have to prove your worth to an employer but competition for jobs does not seem any more difficult now when compared the past decades.
