This is about corruption which is common not only in developed and developing countries but gone uncontrolled in poor countries. Education is the key but it will take time even multiple generations to put an end to corruption or put it in the lowest form.
For hundreds of years, humans came up with many forms of government testing their effectiveness when it comes to power, economy, and populace and nothing came up perfect. Democracy came up as the nearest to perfection but it has its flaws too. But democracy in a fully educated country bound by a population enriched with deep social awareness and responsibility might work.
It's common in poorer or developing countries and this was the reason on why they became poor but not in well developed countries. Education is the key (not the one where people go to school and study) but people needs to be educated for the right people that they will vote whenever there is an ongoing elections.
Education is good so that people can learn to read and write but it cant' really help in terms of finding a job. Many poorer countries lacks of job opportunities and there are people who graduate from several college courses but they are still unemployed for a long time. The change should start with our governments first.
