Education is the key to success. It is the prime differentiation tool. Education is not only about learning. It is about what to learn, how to learn and why to learn. Education is not about transferring knowledge from books to men. Education is all about preparing human resources capable to create knowledge. It is to sensitize learner that knowledge is to apply for human and environmental welfare. It is about developing skills to apply knowledge. It is about shaping attitude that helps environment. It is about ethical application of knowledge. It is about expanding knowledge base. Knowledge is never static. It changes as the human and environmental needs changes. Education goes beyond that. It empower learner to expand horizon of knowledge. It is about building capacity of self learning. Education is about developing attitude to share knowledge and skills. Knowledge is not about information. Knowledge is of two kinds. We know a subject ourselves or we know where we can find information upon it, rather creating new set of information or knowledge is education.

Lots of good things has been said in ancient Indian literature in Sanskrit, which emphasize on assuming responsibility, importance of knowledge and its social application. Some of modern Sanskrit maxims has been developed to reflect and meet the current need and embodied in educational institute's emblem.

तेजस्वि नावधीतमस्तु (tejasvi naavadhiitamastu) means May our knowledge become brilliant.

स्वयं तेजस्विना भवः (swayam tejaswin bhava) means Be self-enlightened.

विद्या ददाति विनयम् (Vidya Dadati Vinayam) means Knowledge generates humility.

योगः कर्मसु कौशलम् (yogaH karmasu kaushalam) means Excellence in action is it self yoga.

विद्या विनियोगात् विकासः (vidyA viniyogAt vikAsaH) means Progress comes from proper application of knowledge.

सुप्रबन्धे राष्ट्र समृद्धि (Suprabandhe rashtra samruddhi)means Better Management for a Better Nation.

सिद्धिर्भवति कर्मजा (siddhirbhavati karmajA) means Success is born of action.

उद्योगः पुरुषस्य लक्षणं (udyogah purushasya lakshanam) means Industry is man's objective.

विद्या विवादाय धनं मदाय शक्ति: परेषां परिपीडनाय |
खलस्य साधोर्विपरीतमेतज्ज्ञानाय दानाय च रक्षणाय ||

A bad person uses his knowledge for (empty) argumentation, his wealth for egotistic actions, and his power for harming others. The opposite is true concerning a good person: He uses his knowledge, wealth, and power for providing to others knowledge, financial help, and protection, respectively.

विद्या विनयेन शोभते (Vidya vinayen shobhate) which highlight humility and politeness as the indicators of of intellectual qualities. Knowledge and wisdom suits well those who are humble and polite.

सिद्धि मुलम प्रबंधनम (Siddhi moolam prabandhanam) means The root of success lies in managament.

विद्यया समाजोत्कर्षः (Vidhyaya samajotkarshah) means The education uplift the society.

The reality in 21st century education system in developing countries on ground says something different. In contrast to developed countries, the education system is becoming obsolete and outdated.  Developing countries has not risen to the occasion. They have failed to satisfy the current needs of society. The governments have failed to make education system that uplift society. There is chaos. Education system is not only behind of its time. It is becoming a ritual. Pass certificate is not proof of education. The curriculum are irrelevant and outdated. The teaching systems are becoming a formalities to transfer and test memory of the students. Infrastructure and teachers are inadequate: in quantity and quality. Private education institutes are money making factories. Examination does not test 'real strength' of the students. The population pressure, faulty education policies and employment-centered education system has eroded foundation of the education. Higher education institutes lacks in research facilities, shamefully the research attitude!

In developed countries, education system emphasize on:
Sensitizing (Teachers and Students) on Real Life situation
Experiential learning
Cooperative learning (Includes sharing knowledge and skills)
Inquiry-based instruction
Technology in the classroom
Behavioural management
Professional development of teachers, management and students
Learner centered education
Cognitive strategies
Critical thinking
Problem solving (knowledge is not to show but demonstrate your abilities)
Attitude to appreciate - (1) there is no one static solution that fits all situation (2) there is life beyond school (3) each situation that you will face will be unique and teacher will not going to accompany you after school (4) Accountability, you are responsible for your actions - you are going to share fruits of success

Developed country's education system focus on critical thinking, problems solving and creating new set of knowledge.Knowledge increases by sharing but not by saving. Knowledge is actually meant to be shared, we keeps on growing by sharing and gaining knowledge continuously, it not only help the other person to improve but polishes our skills as well. Again, a Sanskrit maxim highlights above mentioned argument beautifully articulated in following verse:

न चौर हार्यम न च राज हार्यम |

न भ्रात्रभाज्यम न च भारकारी ||

व्यये कृते वर्धते नित्यं |

विद्या धनं सर्वे धनं प्रधानम् ||

Knowledge can neither be stolen by a thief, nor snatched by a king.

It is indivisible unlike ancestral property, it never burdens the bearer,

it multiplies manifold when offered to others.

Knowledge is the supreme form of wealth.

Developing country also provide freedom to educators coupled with accountability. It support liberal thinking. It is heartening to note that developing country feels pride in practicing traditions under the shadow of false narratives they kill creativity. Examination system in developed country are not solely based on testing memory but creativity, critical thinking, problem solving and liberal views. It is for their own interest; the policy makers, government, regulators, education institutes, faculty members, society and students must learn from the best experience rather than sticking to traditional view on education. I am sure, the investment in education will catapult the development and will provide multiplier effect on returns in long term.  Education is one of the key factors of promoting economic growth because of its role in enhancing human capital thus productivity. The findings of several research indicate that expansion in education expenditure in developing countries affects per per capita GDP positively.

As per OECD report for 2011, five countries spent over 7 percent of their GDP on total education expenditures for all institutions combined are Denmark (7.9 percent), Iceland (7.7 percent), the Republic of Korea (7.6 percent), New Zealand (7.5 percent), and Israel (7.3 percent). The United States spent just
under 7 percent (6.9 percent) of its GDP on total education expenditures.

The countries at bottom of the list whose spending were dismal as their GDP or per capita performance (Bahrain could be exception in due to of its oil-richness)  :

Uganda (2.64%)
Azerbaijan (2.48%)
Bangladesh (2.47%)
Bahrain (2.33%)
Guinea (2.22)
Myanmar (Burma) (2.16%)
Bermuda (1.50%)
DR Congo (1.47%)

The conclusion of the story is worthwhile. If you want to improve your per capita income or GDP and enhance expenditure on education. Learn from the developed countries on revising education policy.
