The term "brain drain” is used as identical to Human capital flight , where the movement of highly educated and skilled expertise is heavily in one direction. [What direction?]
It also suggests the loss of substantial human capital resources without compensation, which results [in] permanent unidirectional flow of skilled labour from less developed countries to developed countries (Salt, 1997).
According to literature, the use of the word “brain”, relates to any talent, know-how, competency or attribute that is a potential asset. While the use of word “drain” conveys a strong implication of serious loss which suggests that this rate of migration is at a greater level than what might be preferred. Therefore, linking the two words together implies the departure of the most skillful experts at noticeable and alarming rates (Johnson, 1965). [I like these sentences!]
Most of the push factors [what kind of factors?] that lead brain drain to happen are often closely related to the characteristics of underdevelopment.
For instance poor condition of services, low wages or salary or misplacement of talent and lack of research facilities. [are these the factors? maybe say these are the factors that lead to brain drain] [Some of these push factors include...]
In contrast pull factors are the ones that attract skilled migrants to their preferred destinations, such as better economic prospects, higher salary and income or modern educational system and opportunity from higher qualification. (SOURCE 11) [this is good]
[Is this just about brain drain in general? Maybe you could include an example of a country experiencing brain drain. I think this is overall a good paragraph!]
