Poor nations experience a great deal of misery with their limited financial resources. They have to prioritize one important task atfor the sake of others.
Most of them find themselves in a critical situation of whether to concentrate on coaching new techniques to their workforce or upgrade their educational system.
However, investment in a country's education model has monumental significance as well. In fact, low literacy rates are among the rootprimary causes of poverty of these underdeveloped countries.
In my opinion, since the topic is
"Should developing countries concentrate on improving industrial skills or should they promote education first ?" , you should make priority and decide which one should be the first. Otherwise your essay might seem to be weak because you choose neither side to make your point.
Hope this help:)
