In inclusion any nation that wants her Economy to grow and develop should invest in the area of capacity development of her citizens by way of setting up quality educational systems, vocational skills that will make her citizens to be ready and fully equipped to develop their nation when given the opportunity.
You are not wrong, but I think you mean to say, @OP Human capital development, not human capacity development.
The two can easily be taken to mean the exact same thing, but not true; there is a slight difference between the two.
I'll explain;
Human capacity development focuses on the development of yourself, maybe your skills or in any other area, for the benefit of yourself, while human capital development still involves the development of your skills, but now as a benefit to the economy of your country, not only yourself.
Here we are talking primarily about the material achievements of humanity and its professional qualities. In our material world, this is certainly very important. However, on a global level, the spiritual component, the inner spiritual world of each person, is important for the development of humanity. Science and technology are constantly developing and here humanity is succeeding. But we are receiving more and more information that we are not the first human civilization on this planet and all previous civilizations perished when science and technology reached levels that we have not even approached yet. That is, the increase in human potential, which is discussed here, invariably led to the death of humanity itself. To prevent this from happening, people need to prioritize our spiritual world so as not to direct the knowledge and experience we have gained to the detriment of the natural environment in which we live and against ourselves.
